실험 절차

To a solution of [[(5)-1-((R)-3,3-dimethyl-5-{4-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl}-[1,3]azasilolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methylester (51.6 mg, 0.096 mmol; Preparation 11) and (R)-4-[5-(4-bromo-2-chloro-5-trifluoromethoxy-phenylcarbamoyl)-pyridin-2-yl]-3-methyl-piperazine-1-carboxylic acid tert-butyl ester (56.7 mg, 0.096 mmol) dissolved in toluene (0.61 mL) and water (0.24 mL) was added potassium carbonate (66.0 mg, 0.48 mmol). The reaction mixture was sparged under nitrogen for 15 min and Pd(dppf)Cl2CH2Cl2 (7.02 mg, 0.009 mmol) was added. 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 oil. The residue was purified by silica gel chromatography (12 g silica, 0% to 100% EtOAc/hexane) to produce the title intermediate as a yellowish solid (23 mg; 26% yield) (m/z): [M+H]+ calcd for C44H54ClF3N8O7Si 927.35 found 927.4.
