Participants

Reaction Steps

A solution of 406 mg (2.13 mmol) of (S)-2-cyclopentyl-1-phenylethanol (from Step C) in 9 mL of pyridine was treated with 1 mL of acetic anhydride. After stirring for 6 h, the reaction was concentrated. Flash chromatography on silica gel using 93:7 v/v hexanes/EtOAc afforded 495 mg (100%) of the title compound: RF: 0.75 (4:1 v/v hexanes/EtOAc); 1H NMR (300 MHz): δ 1.10-1.21 (m, 2H), 1.44-2.04 (m, 9H), 2.05 (s, 3H), 5.75 (dd, J=8.0, 6.1, 1H), 7.25-7.34 (m, 5H).
