Participants

Reaction Steps

A solution of methyl 2-[4-[2-[N-(2-benzoxazolyl)-N-methylamino]ethoxy]phenyl]ethanoate (11.60 g) in dry diethyl ether (200 mL) was added slowly to an ice-cooled, stirred suspension of lithium aluminium hydride (1.36 g) in ether (50 mL) under a nitrogen atmosphere. The mixture was stirred at 0° C. for 20 minutes, then water (10 mL) and hydrochloric acid (2M; 10 mL) were added dropwise with caution. The mixture was diluted with water (200 mL) was the solution adjusted to pH 4 prior to extraction with ethyl acetate (3×200 mL). The combined ethyl acetate solutions were washed with water (2×500 mL), brine (500 mL), dried (MgSO4) and evaporated to afford the title compound, mp 95°-97° C.
