실험 절차

A mixture of 3-(tert-butoxycarbonylamino-methyl)-5-chloro-4-fluoro-benzoic acid (100 mg, 0.3 mmol), HATU (188 mg, 0.5 mmol), dimethylamine (0.2 mL, 2M in THF) and DIPEA (0.23 mL, 1.3 mmol) in DMF (2 mL) was stirred for 16 h at ambient temperature. The crude product was purified without aqueous workup by RP-preparative HPLC (Waters Sunfire, C18-ODB, 5 μm, 30×100 mm, 5-100% CH3CN/H2O/20 min, 100% CH3CN/2 min, CH3CN and H2O containing 0.1% TFA, flow: 40 ml/min) to give the title compound. MS (LC-MS): 275.0 [M−55]+; tR (HPLC conditions c): 4.68 min.
