A solution of p-tolylchloroformate (1.5 mL, 10.3 mmoles) in dichloromethane (15 mL) was added under nitrogen at 0° C. to a stirred solution of 1,2,5,6-tetrahydropyridine-3-carboxaldehyde-O-methyloxime (1.3 g, 9.3 mmoles) and triethylamine (1.3 mL, 2.3 mmoles) in dichloromethane (20 mL). The reaction mixture was stirred at room temperature for 20 minutes, the solvent was evaporated and the residue was partitioned between water and ethylacetate. The organic layer was dried (Na2SO4) and evaporated. The solid was triturated with cyclohexane to afford 2.3 g (91%) of a white solid with mp 70°-71° C.
