Procedure

A mixture of 1.1 g of the compound obtained in step B of EXAMPLE 14, 1 g of 4-(ethoxycarbonylamino)-4-phenylpiperidine trifluoroacetate and 0.7 g of K2CO3 in 3 ml of DMF is heated at 80-100° C. for 2 hours. After cooling to RT, the reaction mixture is poured into water and stirred for 30 minutes and the precipitate formed is wrung, washed with water and dried under vacuum at 60° C. The precipitate is chromatographed on silica H using a DCM/MeOH mixture (from 100/1; v/v to 100/4.5; v/v) as the eluent. The product obtained is dissolved in DCM, a saturated solution of hydrochloric acid in ether is added until the pH is 1, and the precipitate formed is wrung to give 0.52 g of the expected product. M.p.=148-150° C.
