Reaction Steps

A solution of tert-butyl (1-(5-fluoropyridin-2-yl)piperidin-4-yl)carbamate (0.36 g, 1.22 mmol) in HCl in Dioxane (4M, 2 mL), THF (2 mL) and MeOH (2 mL) was stirred at rt. After 4 h the reaction mixture was filtered, the residue washed with EtOAc and dried to give the title compound (0.31 g, 96%) as a solid. 1H NMR (500 MHz, CD3OD): 8.10-8.02 (m, 2H), 7.52 (dd, 1H), 4.34-4.26 (m, 2H), 3.61-3.50 (m, 1H), 3.38 (dt, 2H), 2.28-2.21 (m, 2H), 1.80 (dq, 2H); 13C NMR (CD3OD): 153.2, 151.2, 151.0, 134.5, 134.3, 123.9, 123.6, 115.0, 114.9, 45.3, 29.1; Mass Spectrum: M+H 196.
