実験手順

To a mixture of 4-phenyl-1,3-thiazole-2-carbaldehyde (380 mg, 2.0 mmol), methyl 3-{4-[(4-aminobenzyl)oxy]phenyl}-propanoate (570 mg, 2.0 mmol), acetic acid (0.1 mL), and 1,2-dichloroethane (5 mL) was added sodium triacetoxyborohydride (0.6 g, 2.8 mmol) under ice-cooling, and the mixture was warmed to room temperature and stirred for 1 hr. Propanal (120 mg, 2.1 mmol) and sodium triacetoxyborohydride (0.4 g, 1.9 mmol) were added to the reaction mixture, and the mixture was further stirred at room temperature for 1 hr. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:19-1:2 in volume ratio) to give the title compound (340 mg, yield 68%) as a yellow oil.
