YieldReaction ConditionsOperation in experiment
60% With tributylphosphine; 1,1'-azodicarbonyl-dipiperidine; In toluene; at 40℃; for 5h; General procedure: To a solution of (7-(benzyloxy)chroman-2-yl)methanol 15 (2.65g, 9.80mmol) and ethyl 3-(2-fluoro-4-hydroxyphenyl)propanoate (1.6g, 7.54mmol) in dry toluene (50mL) was added tributyl phosphine (3.77mL, 15.08mmol) and azodicarboxylic acid dipiperidide (3.8g, 15.08mmol). The mixture was stirred at 40C for 5hr, then filtrated. The residue was concentrated in vacuo and purified by column chromatography (ethyl acetate: petroleum ether=1:10) to give compound17(2.27g, 65%) as a colorless oil.
