Reaction Steps
The title product was prepared from 4-(3-aminophenyl)piperidine (released form the correspondent hydrochloride by a standard procedure) and 4-(5-trifluoromethyl-pyridin-2-yloxy)-phenyl chloroformate, preparative HPLC (method C) (reaction performed in a mixture of dichloromethane and dimethylformamide, 5:3). 1.7 M HCl in ethyl acetate was added to the pooled fractions containing the title product, and the fractions was evaporated to dryness (7%, light yellow solid). HPLC-MS m/z=(M+1) 458.0, Rt: 3.09 min.
