실험 절차

To a mixture of 4-fluoro-3-{[2-(pyridin-2-ylamino)-thiazol-5-ylmethyl]-amino}-benzoic acid (compound 52A, 21 mg, 0.06 mmol) and HATU (38 mg, 0.1 mmol) in DMF (0.2 ml) and THF (0.4 ml), were added 2,2-difluoro-1,3-propanediamine (ref. Tetrahedron, 8617, 1994) (60 mg, 0.54 mmol) and DIPEA (26 mg, 0.2 mmol). The resulting mixture was stirred at RT for 18 h, then diluted with CH2Cl2, washed with brine, dried over Na2SO4 and concentrated. The residue was purified by flash column chromatography [silica gel, 5% (NH3/MeOH(2M) in EtOAc] to afford the title compound (17 mg, 65%) as a white solid. LC/MS; (M+H)+=437.
