Diisopropylethylamine → HCID 86726721, 화합물

To a mixture of 5-[(tert-butoxycarbonyl)amino]-2-(2,6-difluorophenyl)-1,3-thiazole-4-carboxylic acid (Example 1, step 6) (47.3 mg, 0.133 mmol), tert-butyl [(3S,5R)-1-(5-amino-2,3-dihydrofuro[2,3-b]pyridin-4-yl)-5-methylpiperidin-3-yl]carbamate (41.0 mg, 0.118 mmol) and HATU (142.3 mg, 0.3742 mmol), DMF (2.0 mL) was added followed by DIPEA (115.8 mg, 0.8960 mmol). The reaction mixture was stirred at room temperature for 2 h, and then concentrated under reduced pressure. DCM (2.0 mL) was added to the residue followed by TFA (2.0 mL). The mixture was stirred at room temperature for 30 min., and then concentrated under reduced pressure. The resulting residue was purified using RP-HPLC (XBridge™ C18 column, eluting with a gradient of MeCN/water containing 0.1% NH4OH, at flow rate of 30 mL/min.) to afford the title compound as a white solid (25.2 mg, 44%). LCMS calc. for C23H25F2N6O2S (M+H)+: m/z=487.2. found 487.2.
