실험 절차

A suspension of 362 (0.90 g, 2.3 mmol), amine 363 (0.93 g, 5.7 mmol) [amine 363 has been synthesized according to the procedures used for the synthesis of amines 322 (scheme 18) and 326 (scheme 20)] and acetic acid (0.26 ml, 4.6 mmol) in dichloromethane (50 ml) was stirred for 1 h at room temperature. Then sodium triacetoxyborohydride (1.45 g, 6.85 mmol) was added and the mixture was stirred at r.t. for 16 h. A further amount of sodium triacetoxyborohydride (1.5 g) was then added, and stirring continued for 2 h. The reaction mixture was partitioned between dichloromethane and 1N HCl. The organic phase was discarded. The aqueous phase was basified (pH=13) with 3M NaOH, and extracted with dichloromethane. The organic extract was dried over anhydrous sodium sulfate, filtered, and concentrated to yield 364 (0.72 g, 58%) as a yellow solid. LRMS (M+H): 542.4
