反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To the solution of N-(4-iodo-pyridin-3-yl)-N-methyl-3,5-bis-trifluoromethyl-benzamide (150 mg, 316 μmol, example 36, intermediate a) in DME (3 mL) was added 2-(2-(tert-butyldimethylsilyloxy)ethyl)phenylboronic acid (88.7 mg, 316 μmol, CAS RN 913835-62-8) and 2M aqueous Na2CO3 solution (1 mL). The reaction mixture was stirred under argon atmosphere for 15 minutes. Pd(II)acetate (3.55 mg, 15.8 μmol) and triphenylphosphine (8.3 mg, 31.6 μmol) were added. The reaction mixture stirred at 90° C. for 18 hours and then poured on 30 mL 1M aqueous HCl and 30 mL EtOAc. The layers were separated and the aqueous layer was extracted a second time with 30 mL EtOAc. The organic layers were washed with 30 mL brine, dried over MgSO4, filtered and concentrated under vacuum. The compound was purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 60:40). Colorless solid (95 mg, 52%). MS (ESI): m/z=469.134 [M+H]+. The reaction mixture stirred at 90° C. for 18 hours The layers were separated the aqueous layer was extracted a second time with 30 mL EtOAc The organic layers were washed with 30 mL brine dried over MgSO4 filtered concentrated under vacuum The compound was purified by silica gel chromatography eluting with a gradient of n-heptane:EtOAc (100:0 to 60:40)
