Participants

Reaction Steps

33.0 g (0.1 mol) of benzyl 4'-acetyl-4-biphenylcarboxylate, 200 ml of tetrahydrofuran and 50 ml of ethanol were supplied into the same flask as used in Example 9. Then 3.8 g (0.1 mol) of sodium borohydride was added at 15°-25° C. over a period of 10 minutes. After standing at the same temperature for 2 hours, the reaction solution was poured into ice-water and extracted twice with 300 ml of chloroform. The organic layer was washed with water and concentrated under reduced pressure to obtain 32.9 g (99% yield) of benzyl 4'-(1-hydroxyethyl)-4-biphenylcarboxylate (III-15).
