Procedure

(S)-tert-butyl 2-(4-(3-(4-fluorophenyl)-1H-1,2,4-triazol-1-yl)phenyl)morpholine-4-carboxylate (201 mg, 0.47 mmol) was dissolved in dioxane (0.5 ml) and a solution of HCl in dioxane (4M, 1.75 ml, 7.1 mmol) was added. The reaction mixture was stirred for 3 h at 60° C. After cooling ether (2 ml) was added and the solid was filtered off. It was washed with ether and dried in vacuo to afford (S)-2-(4-(3-(4-fluorophenyl)-1H-1,2,4-triazol-1-yl)phenyl)morpholine hydrochloride as a white solid (170 mg, 99%). MS (ISP): 325.2 ([M+H]+).
