実験手順

To a solution of [(S)-2-Methyl-1-((S)-4-methyl-2-{4-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl}-2,5-dihydro-pyrrole-1-carbonyl)-propyl]-carbamic acid methyl ester (100 mg, 0.20 mmol, Preparation 4) and (R)-4-[5-(4-bromo-2-chloro-5-trifluoromethoxy-phenylcarbamoyl)-pyridin-2-yl]-3-methyl-piperazine-1-carboxylic acid tert-butyl ester (110 mg, 0.19 mmol) dissolved in toluene (1.18 mL) and water (0.43 mL) was added potassium carbonate (127 mg, 0.92 mmol). The reaction mixture was sparged under nitrogen for 15 min and Pd(dppf)Cl2 CH2Cl2 (13.55 mg, 0.017 mmol) was added and the reaction mixture was sparged with nitrogen and heated to 90° C. overnight, cooled to RT, diluted with EtOAc and washed with water and brine to produce a dark colored solid, which was purified by silica gel chromatography (12 g silica, EtOAc/hexanes 40 to 100%) to produce the title intermediate (51 mg, 31% yield) as a yellowish colored solid. (m/z): [M+H]+ calcd for C44H50ClF3N8O7 895.34 found 895.3.
