Procedure
To a solution of 7-methoxy-2-phenyl-1H-quinolin-4-one (1.5 g, 6 mmol) in DMF (11 ml) were added successively K2CO3 (1.66 g, 12 mmol) and (RS)-epichlorohydrin (1.9 ml, 24 mmol). The reaction mixture was stirred at 65° C. for 3 hours, then cooled to room temperature and diluted with CH2Cl2 (25 ml). Solid was filtrated, and filtrate was concentrated. The residue was chromatographed over silica gel (hexane-ethyl acetate, 4:1) to provide (RS)-7-methoxy-4-oxiranylmethoxy-2-phenyl-quinoline (1.05 g, 57%) as a colorless oil, MS: m/e=307 (M+).
