Reaction Steps

2-Bromo-4-methyl-benzonitrile was coupled to piperazine using Preparation 1A Buchwald chemistry to afford 4-(2-cyano-5-methyl-phenyl)-piperazine. 4-(2-cyano-5-methyl-phenyl)-piperazine is converted to 4(2-hydroxymethyl-5-methyl-phenyl)-piperazine in a manner similar to preparation 54A Steps 1 and 2.4-(2-Hydroxymethyl-5-methyl-phenyl)-piperazine was converted to the title compound in a manner similar to Preparation 60A except that pyrrolidine was used to displace the mesylate. LRMS (ESI+): 360.3 (M+1)
