Procedure

A solution of (S)-N-[2-(7-allyl-5-bromo-6-hydroxyindan-1-yl)ethyl]propionamide (588 mg, 1.67 mmol.) in methanol (30 mL) was cooled to about -70° C., to which was introduced ozone for 5 minutes. After confirming the disappearance of the starting material, an excess amount of powdery sodium borohydride (510 mg, 13.4 mmol.) was added to reaction mixture at about -70° C. to decompose ozonide. The reaction mixture was warmed to room temperature, which was neutralized with dilute hydrochloric acid, followed by extracting the organic matter with a mixture of ethyl acetate:butanol=1:1. The extract solution was dried over anhydrous magnesium sulfate, from which the solvent was distilled off under reduced pressure. The residue was then washed with diethyl ether to afford the title compound (yield 0.59 g, 99%).
