Procedure
560 mg tert-butyl 4-(4,5-diphenyloxazol-2-yl)-piperidine-1-carboxylate are placed in 2 ml dichloromethane, then 1.1 ml trifluoroacetic acid are added. The reaction mixture is stirred for 15 hours at ambient temperature, then evaporated to dryness. The residue is combined with toluene and evaporated to dryness again. The residue is mixed with diethyl ether and the precipitated solid is suction filtered and dried. 510 mg (V-10) are obtained. Analytical HPLC-MS (method B): RT=1.38 min.
