To a stirred solution of tert-butyl 4-((6-chloropyridin-3-yl)oxy)piperidine-1-carboxylate (1.0 g, 3.2 mmol) in dichloromethane (10 mL), trifluoroacetic acid (3 mL) was added at 0° C. and stirred for 3 h. The reaction mixture was concentrated in vacuo and resultant residue was dissolved in MeOH (5 mL), 2,2-dimethyloxirane (0.246 g, 3.2 mmol) was added and stirred at room temperature for 10-12 h. The reaction mixture was concentrated in vacuo to give the title product (0.775, 85%); MS: 285.0 (M+1).
