実験手順

To a solution of (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) and ((S)-2-methyl-1-{(2S,4S)-4-methyl-2-[7-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-naphtho[1,2-d]imidazol-2-yl]-pyrrolidine-1-carbonyl}-propyl)-carbamic acid methyl ester (100 mg, 0.19 mmol) dissolved in toluene (1.19 mL) and water (0.43 mL) was added potassium carbonate (128 mg, 0.93 mmol). The reaction mixture was sparged with nitrogen for 15 min and Pd(dppf)Cl2 CH2Cl2 (13.6 mg, 0.017 mmol) was added. The reaction mixture was sparged with nitrogen, heated at 90° C. overnight, cooled to RT, diluted with EtOAc and washed with water and brine to produce a dark colored oil, which was purified by silica gel chromatography (24 g silica, 40% to 100% EtOAc/hexane) to produce the title intermediate (101 mg; 59% yield) as a yellow solid. (m/z): [M+H]+ calcd for C46H52ClF3N8O6 921.36 found 921.3.
