실험 절차

To a mixture of 5-[(tert-butoxycarbonyl)amino]-2-(2,6-difluorophenyl)-1,3-thiazole-4-carboxylic acid (Example 1, Step 6, 418.2 mg, 1.174 mmol), tert-butyl [(3S)-1-(5-amino-2,3-dihydrofuro[2,3-b]pyridin-4-yl)piperidin-3-yl]carbamate (377.4 mg, 1.128 mmol) and HATU (1308 mg, 3.440 mmol), DMF (15.0 mL) was added, followed by DIPEA (1.00 mL, 5.74 mmol). The mixture was stirred at room temperature for 2 h. The reaction mixture was then diluted with EtOAc (150 mL), washed with saturated aq. NaHCO3 (150 mL) and brine (2×75 mL), then dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by chromatography on silica gel (0-100% EtOAc in hexanes) to give the sub-title compound as a yellow solid (720.2 mg, 95%). LCMS calc. for C32H39F2N6O6S (M+H)+: m/z=673.3. found 673.2.
