참여 물질

반응 단계

A mixture of 3,4-diaminopyridine (1.1 g, 10.1 mmol), 1-benzyl-4-piperidone (3.2 g, 16.9 mmol) sodium triacetoxyborohydride (4.0 g, 18.9 mmol), and acetic acid (10.7 mL) in dichloroethane (10 mL) was stirred for about 6 days at room temperature. The reaction was concentrated to near dryness, and partitioned between chloroform (5×50 mL) and 1N sodium hydroxide (50 mL). The organic phase was dried over magnesium sulfate and concentrated to give the title compound (2.8 g). MS 283 (M+1).
