To a suspension of tert-butyl (3-cyano-1,5-dimethoxypentan-3-yl)carbamate (G20, 192 mg) and cobalt(II) chloride (183 mg) in methanol (7 mL), sodium borohydride (134 mg) was added at room temperature, and the mixture was stirred at the same temperature for 4 hours. To the reaction mixture, ethyl acetate and 1.0 mol/L aqueous sodium hydroxide were added. The organic layer was separated, washed with saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to obtain tert-butyl (3-(aminomethyl)-1,5-dimethoxypentan-3-yl)carbamate (G21, 275 mg).
