合成路线1
该中间体在本合成路线中的序号：(III)The intermediate monoprotected diaminopyridine (V) was prepared as shown in Scheme 1. After protection of 4-(aminomethyl)pyridine (I) as the tert-butyl carbamate (II) by means of Boc2O, reaction with peracetic acid yielded the corresponding pyridine N-oxide (III). Subsequent treatment of (III) with trimethylsilyl cyanide and dimethylcarbamyl chloride produced nitrile (IV), which was reduced to the required amine (V) by hydrogenation over Raney-Ni in the presence of ethanolic ammonia.
