Reaction Steps

A mixture of benzyl 4-(aminomethyl)piperidine-1-carboxylate (EXAMPLE 13, Step 1) (1.25 g, 5.04 mmol) and 2,3-dichloropyrazine (0.25 g) was heated to 100° C. for 1 h. The reaction mixture was cooled and partitioned between EtOAc and pH5.2 citrate buffer. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and the solvent evaporated to give a crude product. Purification by flash column chromatography (5–50% EtOAc hexane) afforded the title compound. M.S (M+1): 361.
