Procedure

A mixture containing 7.0 g. of β-chloromethylnaphthalene, 6.56 g. of 2-pyridylpiperazine and 4.4 g. of sodium carbonate in 40 ml. of dimethylformamide is stirred on a steambath for 90 minutes. The reaction mixture is filtered and the filtrate stirred with ice water. The precipitate was filtered and recrystallized from isobutyl alcohol to yield 1-(β-napthylmethyl)-4-(2-pyridyl)piperazine having a melting point of 124°-126° C.
