Reaction Steps

(Z)-2,6-dimethoxy-4-(3,4,5-trimethoxystyryl)phenol (38b) (346.37.36 mg 1.0 mmol) in DMF (20 mL) was added anhydrous potassium carbonate (690 mg, 5.0 mmol) and 2-[4-(5-Bromo-pentyloxy)-3-methoxy-phenyl]-2,3-dihydro-1H-quinazolin-4-one (2d) (419.29 mg, 1.0 mmol). The reaction mixture was stirred at a temperature of 30° C. for 30 h and the reaction was monitored by TLC using ethyl acetate-hexane (6:4) as a solvent system. Then to this ice is added and extracted with ethyl acetate. The solvent was evaporated under vacuum to afford the crude product. This was further purified by column chromatography using ethyl acetate:hexane (6:4) as a solvent system to obtain the pure product (43d) (546 mg, 80% yield).
