To a solution of methyl 2-(5-(2,3-dichlorophenyl)pyridin-3-yl)cyclopropanecarboxylate (270 mg, 0.838 mmol) in MeOH (3 ml) was added NaOH (5 M in water, 0.503 ml, 2.51 mmol) at room temperature. The resulting mixture was stirred at room temperature for 30 min. The reaction was quenched by the addition of HCl (5 M in water), and the mixture was extracted with AcOEt/trifluoroethanol (10:1). The extract was washed with water and brine, dried over Na2SO4, filtered and concentrated in vacuo. The resulting crude was dissolved in toluene (7 ml). Diphenylphosphonoazide (0.272 ml, 1.257 mmol), triethylamine (0.175 ml, 1.257 mmol) were added to the solution, which was stirred for 12 h at 100° C. Benzyl alcohol (0.523 ml, 5.03 mmol) was added to the reaction mixture and this mixture was stirred for additional 4 h. A saturated NaHCO3 solution was added at room temperature and the mixture was extracted with AcOEt. The extract was washed with water and brine, dried over Na2SO4, filtered and concentrated in vacuo. Purification by flash column (EtOAc/Heptane=0-50%, v/v) gave benzyl 2-(5-(2,3-dichlorophenyl)pyridin-3-yl)cyclopropylcarbamate (94.1 mg, 0.228 mmol, 27% yield) ESI-MS m/z: 413[M+1]+. 1H NMR (CDCl3, 400 MHz) ppm 1.27-1.33 (m, 2H), 2.15-2.28 (m, 1H), 2.81-2.87 (m, 1H), 5.13 (s, 2H), 7.21 (bs, 1H), 7.29 (t, J=8.0 Hz, 1H), 7.35 (s, 5H), 7.52 (dd, J=8.0, 0.6 Hz, 2H), 8.48 (s, 2H)
