HCID 117924541-benzyl-4-[N-propyl-N-(3-nitro-2-pyridinyl)amino]piperidine

Procedure

Following the general procedure of EXAMPLE 70, and making non-critical variations but substituting 1-benzyl-4-(propylamino)piperidine (EXAMPLE 112) for 1-benzyl-4-(methylamino)piperidine and 2-chloro-3-nitropyridine for 2-bromo-3-ethoxypyridine and using a reaction time of 10 min, the title compound is obtained, C,H,N: Anal. Calcd for C20H26N4O2 : C=67.77, H=7.39, N=15.81-found: C=67.44, H=7.42, N=15.60.
