Procedimiento

(R)-Phenyl-phenylamino-acetic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (Diastereoisomer 1 of C2) (75.0 mg, 0.22 mmol) and 2-bromo-1-(2-methylthiazol-4-yl)ethanone (I228) (49.1 mg, 0.22 mmol) in acetonitrile (5 mL) is heated at 100° C. for 75 minutes under microwave irradiation (UPLC-MS monitoring: complete conversion). The solvent is removed and the resulting brown solid is tritured with iPr2O/Et2O (1/1) and then with iPrOH to obtain the title compound as a grey powder (43.3 mg, 35% yield, bromide salt, single diastereoisomers).
