To a solution of 4-methyl-phenyl-amino-phenyl-acetic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (C245) (63.5 mg, 0.18 mmol) in acetonitrile (5 mL), is added 2-bromo-1-phenyl-ethanone (36 mg, 0.18 mmol) and the mixture was heated at 100° C. for 1 hour in a MW oven (UPLC-MS monitoring: complete conversion). Solvent is evaporated and the resulting crude is purified by flash chromatography (DCM/MeOH=95/5) to obtain the title compound as a white solid (58 mg, 32% yield, bromide salt, mixture of diastereoisomers).
