143.5 mg (0.56 mmol) of N-(3-bromophenyl)-2,2-dimethylpropanamide, 142.2 mg (0.56 mmol) of bis(pinacolato)diboron, 119.1 mg (1.21 mmol) of potassium acetate, 13.7 mg (0.02 mmol) of PdCl2(dppf), 150.0 mg (0.37 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 8A), 0.93 ml of 2 M sodium carbonate solution and a further 13.7 mg (0.02 mmol) of PdCl2(dppf) in 2.0 ml of DMF are reacted by general method D. An initial purification by preparative HPLC is followed by column chromatography on silica gel (mobile phase: dichloromethane/methanol/ammonia 90:9:1). Drying under high vacuum results in 32.4 mg (17% of theory) of the title compound.
