Reaction Steps

A solution of 4-bromo-3-(morpholinosulfonyl)-N-((1S,4R)-1,3,3-trimethylbicyclo-[2.2.1]heptan-2-yl)benzamide 91 (400 mg, 0.8 mmol), bis(triphenylphosphine)-palladium(II) chloride (30 mg, 0.04 mmol), triphenylphosphine (39.7 mg, 0.151 mmol), copper(I) iodide (9 mg, 0.04 mmol), N-ethylethanamine (1.18 mL, 11.4 mmol) in N,N-dimethylformamide (1 mL) was degassed with nitrogen and sonicated. The reaction mixture was heated in the microwave at 125° C. for 25 minutes. The reaction mixture was poured into saturated ammonium chloride solution and extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4, filtered and evaporated. The residue was purified by silica gel chromatography using hexane/ethyl acetate (0-50%) to give the product 6.1 as a yellow oil (240 mg, 60% yield).
