实验步骤: A mixture of 2-bromo-N-(2,6-difluoro-phenyl)-acetamide (Example 38a) (42 mg) and 1-phenyl-cycloheptanecarboxylic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (Example 14e) (50 mg) in MeCN (1 mL) was stirred at room temperature for 19 h. A further 20 mg 2-bromo-N-(2,6-difluoro-phenyl)-acetamide was added and stirring continued for another 22 h. The volatiles were evaporated and the residue was purified by silica gel chromatography eluting with 0-10% MeOH/dichloromethane to give the title compound (41 mg) as a colourless foam. stirring continued for another 22 h The volatiles were evaporated the residue was purified by silica gel chromatography eluting with 0-10% MeOH/dichloromethane

实验步骤: To a mixture of 2,6-difluoroaniline (1.12 g) and potassium carbonate (1.8 g) in 50 mL dichloromethane was added bromoacetyl bromide (1.5 mL) and the mixture was stirred at room temperature for 17 h. Water was added and the mixture stirred for several hours then the phases were separated on a hydrophobic frit and the organic layer was evaporated. The crude product was purified by silica gel chromatography eluting with 0-100% EtOAc/cyclohexane to give the sub-titled compound (0.92 g) as a white solid. the mixture stirred for several hours the phases were separated on a hydrophobic frit the organic layer was evaporated The crude product was purified by silica gel chromatography eluting with 0-100% EtOAc/cyclohexane
