Sodium sulfate decahydrate → 1-{5-Chloro-2-[(1-methylethyl)sulfanyl]phenyl)methanamine hydrochloride

Participants

Reaction Steps

(Step 2) To a suspension of lithium aluminum hydride (1.56 g) in tetrahydrofuran (250 ml) was added a solution of 5-chloro-2-[(1-methylethyl)sulfanyl]benzonitrile obtained in Step 1 (7.25 g) in tetrahydrofuran (50 ml) at 0° C. The mixture was stirred at room temperature for 3 hr, and treated with sodium sulfate 10 hydrate. The mixture was further stirred at room temperature for 30 min, and the inorganic substance was filtered off through celite. The filtrate was concentrated under reduced pressure. The residue was dissolved in methanol, 4N hydrogen chloride-ethyl acetate solution (15 ml) was added, and the solvent was evaporated under reduced pressure. The obtained solid was washed with a mixed solvent of diisopropyl ether-ethyl acetate to give 1-{5-chloro-2-[(1-methylethyl)sulfanyl]phenyl}methanamine hydrochloride (6.57 g).
