A mixture of N-[(2S)-5-hydroxy-2,3-dihydro-1H-inden-2-yl]-2-propanesulfonamide (700 mg, 2.74 mmol, Description 3) and (6-methyl-3-pyridinyl)methanol (338 mg, 2.74 mmol) in dichloromethane (30 ml) was stirred under argon at room temperature, Triphenylphosphine (719 mg, 2.74 mmol) and diisopropyl azodicarboxylate (0.533 ml, 2.74 mmol) were then successively added. The resulting mixture was stirred at room temperature under argon for 16 hours. The reaction mixture was washed with water, dried over sodium sulphate, filtered and evaporated. The desired product was purified by SCX column eluting with 1 M ammonia in methanol solution and column chromatography on silica using 1 to 99% ethyl acetate in n-pentane to give a white solid. The free base solid was dissolved in methanol and treated with ethereal hydrochloride to give the title compound (554 mg).
