2-bromo-4-chloro-1-(difluoromethyl)benzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 463 mg (purity 93%, 2.3 mmol) of (5-chloro-2-methoxypyridin-4-yl)boronic acid and 515 mg (2.1 mmol) of 2-bromo-4-chloro-1-(difluoromethyl)benzene in the presence of [1,1-bis(diphenylphosphino)ferrocene]palladium(II) chloride/dichloromethane monoadduct were reacted according to General Method 2A. Yield: 305 mg (purity 77%, 34% of theory)

Conditions: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of Intermediate 14A (0.88 g, 3.64 mmol) in DMF (10 mL) was added tert-butyl acrylate (1.401 g, 10.93 mmol), TEA (1.270 mL, 9.11 mmol) and Pd(OAc)2 (0.082 g, 0.364 mmol). The reaction was warmed to 90° C. After 5 h, the reaction was cooled to rt and then filtered to remove the solid. The filtrate was diluted with EtOAc, washed with 1M HCl, saturated NaHCO3, and brine. The organic phase was dried over MgSO4, filtered and concentrated. Purification by normal phase chromatography gave Intermediate 14B (232 mg, 22% yield) as a tan oil. MS (ESI) m/z: 233.1 (M-tBu)+. the reaction was cooled to rt filtered to remove the solid The filtrate was diluted with EtOAc washed with 1M HCl, saturated NaHCO3, and brine The organic phase was dried over MgSO4 filtered concentrated Purification by normal phase chromatography
