Procedure

To a solution of tert-butyl 4-(4-(4-carbamoyl-2-(2,6-difluorophenyl)oxazol-5-yl)benzyl)piperazine-1-carboxylate (0.100 g, 0.2 mmol) in DCM (3 mL) was added 4M HCl in dioxane (2 mL, 8.0 mmol) and the resulting mixture stirred at room temperature overnight. The solvent was removed in vacuo. The residue was purified by preparative HPLC to afford 2-(2,6-difluorophenyl)-5-(4-(piperazin-1-ylmethyl)phenyl)oxazole-4-carboxamide (0.043 g, 0.1 mmol, 50%) as a white solid as the formate salt. 1H NMR (DMSO) 2.44 (4H, m), 2.88 (4H, m), 3.55 (2H, s), 7.40 (2H, t), 7.47 (2H, d), 7.75 (3H, m), 8.19 (2H, d), 8.32 (1H, s). LCMS (2) Rt: 2.63 min; m/z (ES+) 399.
