Benzylamino-phenyl-acetic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (C80) (100 mg, 0.28 mmol) is dissolved in ethyl acetate (1.90 mL) and acetonitrile (0.95 mL) and ethyl 5-(2-bromoacetyl)isoxazole-3-carboxylate (82.0 mg, 0.31 mmol) is added. The orange solution is stirred at RT overnight. The suspension is evaporated and the crude is purified by flash chromatography (DCM/EtOH=93/7) to obtain the title compound as a pale brown solid (61 mg, 35% yield, bromide salt, mixture of diastereoisomers).
