Procedure

To a mixture of 3-amino-4-[(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-(trifluoromethyl)piperidin-1-yl]-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (86.6 mg, 0.189 mmol), 5-[(tert-butoxycarbonyl)amino]-2-(2,6-difluorophenyl)-1,3-thiazole-4-carboxylic acid (89.5 mg, 0.251 mmol), and HATU (221.8 mg, 0.5833 mmol) was added DMF (2.0 mL) followed by DIPEA (164.3 mg, 1.271 mmol). The reaction mixture was stirred at 45° C. for 14 h, and then concentrated under reduced pressure. The resulting residue was purified by chromatography on silica gel (0-100% EtOAc in hexanes) to give the sub-title compound as a dark semi-oil (110.3 mg, 73%). LCMS calc. for C36H42F5N6O7S (M+H)+: m/z=797.3. found 797.3.
