Reaction Steps

To a solution of (R)-2-azidomethyl-8-(2-chloro-phenyl)-6-fluoro-chroman (210 mg, 0.67 mmol) in tetrahydrofuran (10 mL) and water (0.5 mL) was added triphenylphosphine (0.26 g, 10 mmol) and the reaction mixture stirred at room temperature for 24 hours. The solvent was removed under vacuum to form a colorless oil. Chromatography with 0–5% methanol in methylene chloride plus 1% NH4OH afforded {[(R)-8-(2-chlorophenyl)-6-fluoro-2H-chromen-2-yl]methyl}amine as a colorless oil. The colorless oil was dissolved in ethyl acetate and made into its hydrochloride salt (56 mg, 25%) as a beige solid using excess ethereal hydrochloric acid, mp 145–147° C.; [α]D25=+256.01° (c=5.3 mg/0.7 mL MeOH).
