Procedure

Lithium aluminium hydride (1M in THF. 1.5 ml) was added dropwise to a stirred solution of 4-[3-(4-(4-cyanobenzyl)phenylthio)-5-fluorophenyl]-4-methoxytetrahydropyran (0.675 g) in THF (9 ml) and the mixture was stirred at ambient temperature for 1 hour. Water (5 ml) and 4N aqueous sodium hydroxide solution (5 ml) were added in turn. The mixture was extracted with diethyl ether. The organic phase was washed with water, dried (MgSO4) and evaporated. The residue was dissolved in diethyl ether (5 ml) and a solution of oxalic acid in diethyl ether was added. The precipitate was isolated. There was thus obtained the mono-oxalate salt of 4-[3-(4-(4-aminomethylbenzyl)phenylthio)-5-fluorophenyl]-4-methoxytetrahydropyran (0.34 g), m.p. 142°-146° C.
