To a solution of (R)-phenyl-phenylamino-acetic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (Diastereoisomer 1 of C2) (50 mg, 0.15 mmol) in acetonitrile (1 mL), is added 2-bromo-1-(2,4-difluoro-phenyl)-ethanone (35 mg, 0.15 mmol) and the mixture reacted in a closed vessel under MW irradiation for 1 hour at 100° C. (UPLC-MS monitoring: complete conversion). The 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 (37.3 mg, 44% yield, bromide salt, single diastereoisomer).
