N'-t-butyl-N-benzoyl hydrazine (1.2 g), 2-chloromethyl pyridine (1.0 g) and triethylamine (2 equivalents) were stirred in dimethyl sulfoxide (15 ml) at room temperature for 2 hours. The reaction mixture was then warmed to 50° C. for 2 hours. The mixture was diluted with ether and washed with water. The organic layer was dried over magnesium sulfate, filtered and rotavapped to afford a yellow oil. The oil was chromatographed on silica gel (G:70-230 mesh) using a methylene chloride-ether mixture (1:1) as eluant to afford the purified product as a yellow gum in approximately 20% yield.
