Added 1N NaOH (50 ml, 50 mmol) and Chloroacetyl chloride (3 ml, 37.7 mmol) in CH2Cl2 (50 ml) dropwise to a solution of 5-(1-methyl-1H-1,2,4-triazol-3-yl)-2-(1,2,3,6-tetrahydropyridin-4-yl)pyridine dihydrochloride (5BX) (1 g, 3.60 mmol) in CH2Cl2 (50 ml at 0° C., maintaining pH at >12. Mixture was stirred for 2 hours at 0° C., then reaction was diluted with CH2Cl2 (200 ml) and H2O (100 ml). The organic layer was separated, washed with H2O (50 ml), dried (Na2SO4), filtered and solvent evaporated yielding title product as a white solid (1.1 g, 100%) MS (MH, 318)
