With potassium hydroxide; In ethanol; for 10h;Reflux; | 1,3-Diphenyl propen-2-one (0.01mol) (1) were taken in a 250 mL round bottom flask and dissolved in ethanol (25 mL). To this guanidine chloride (0.01 mol) and ethanolic KOH (5 mL of 40 %) were added. The reaction mixture was refluxed for 10 h. The mixture was then poured into water (ice-cold) and neutralized with dil. HCl. After neutralization, the solid was filtered, washed with excess of water, dried and recrystallized from ethanol from ethanol to give pure product. Spectral data for compound 2: The IR of compound 2 exhibited nu (C=C) stretching = 1537-1494 cm-1, nu(N-H) (1 amine) stretching = 3302 cm-1 and 3475 cm-1, nu (C-N) stretching = 1220.98 cm-1, nu(C-H)(Sp2) stretching = 3180.72 cm-1. 1H NMR (400 MHz, DMSO-d6) delta ppm: 3.43 (s, 3H,-OCH3), 5.1 (s, 2H, -NH2), 7.0 to 8.0 (m, 20H, Ar-H and NH) [9]. |

34% | With triethylamine; In 1,4-dioxane;Heating / reflux; | To a solution of <strong>[40230-24-8]2-amino-4,6-diphenylpyrimidine</strong> (0.202 mmol, 1 eq. ) in 1,4- dioxane (5mL) was added triethylamine (0.223 mmol, 1.1 eq. ), followed by the appropriate acid chloride (0.304 mmol, 1.5 eq. ). This was then stirred at reflux until no starting material was visible by TLC. Upon completion, the reaction mixture was separated between ethyl acetate (20 mL) and water (20 mL). The aqueous layer was further extracted with ethyl acetate (2 x 20 mL) and the combined organics washed with water and brine. After drying over MgSO¢ and evaporation under reduced pressure, the crude product was purified by column chromatography, eluting with a petroleum ether-ethyl acetate or a dichloromethane-methanol solvent system. Recrystallisation with ethanol or petroleum ether-ethyl acetate gave the corresponding amide in crystalline form. N- (4, 6-Diphenyl-pyrimidin-2-yl) -benzamide (9).

31% | With sodium hydroxide; In ethanol; water; for 6h;Heating / reflux; | A mixture benzylidenacetophenone (38. 6 g, 0.185 mol, 1.1 eq. ) and guanidine hydrochloride (16 g, 0.168 mol, 1 eq. ) were refluxed in ethanol (150 mL). Sodium hydroxide (21.6 g, 0.539 mol, 3.2 eq. ) was dissolved in a minimum amount of water (40mL), and added dropwise to the refluxing mixture. The reaction mixture was then stirred at reflux for a further 6 h. Upon cooling, the reaction mixture was concentrated and then separated between ethyl acetate (200 mL) and water (200 mL). The aqueous layer was then extracted with ethyl acetate (2 x 100 mL). The combined organics were washed with water (200 mL) and brine (200 mL), dried over MgSO¢, and concentrated in vacuo. The crude product was then purified by column chromatography on Si02, eluting with dichloromethane. Recrystallisation from ethyl acetate gave clear colourless crystals yield 31% ; 1H NMR 8 (CDCIs) : 8. 09-8.04 (m, 4H, Ar), 7.54- 7.48 (m, 7H, Ar), 5. 25 (br s, 2H, NH2). |
