Reaktionsschritte
Operations are carried out as for Example 7, starting from 2.5 g of 1-phenyl isoquinoline 3-carboxylic acid, 2.86 g of triethylamine, 1.24 g of ethyl chloroformate and 1.93 g of 2(R)-ethyl piperidine hydrochloride in 100 ml of toluene. After chromatography, 2 g of 2(R)-ethyl 1-[(1-phenyl 3-isoquinolyl) carbonyl]piperidine in the form of oil are obtained. αD26 =+1.4° (2% in ethanol).
