Participants

Reaction Steps

To a solution of 1, 2, 3, 4-tetrahydro-2-naphthalencarboxylic acid[6-(2-nitrobenzenesulfonylamino)-hexyl]-amide (0.090 g, 0.19 mmol) in tetrahydrofuran (5 mL) cooled to 0° C. was added 2 mL 1M solution of borane:THF complex and the reaction mixture was refluxed for 12 h. The reaction mixture was cooled in an ice bath and quenched with 2 mL of 1N HCl. The reaction mixture was neutralized with 10% aqueous sodium hydroxide solution and extracted with ethyl acetate (3×25 mL). The organic phase was washed with brine, dried over sodium sulfate, and evaporated in vacuo to afford an oil which was purified by preparative TLC to afford the titled compound (0.06 g,70%); hydrochloride salt mp (162-163° C.).
