Procedure

A mixture of 5 g of 5-(3,4-dimethoxyphenyl)-4,4-dimethyl-2-piperidin-4-yl-2,4-dihydro-3H-pyrazol-3-one hydrochloride (compound B1), 1.9 ml of triethylamine and 2.5 g of N-BOC-glycine in 25 ml of DCM is stirred until complete dissolution (about 15 min). 3.9 g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride is added and the resulting mixture is stirred at RT for 3 h. After washing with 1 M sodium carbonate, the organic layer is dried over magnesium sulphate and evaporated. The residue is purified by column chromatography [silica, ethyl acetate]. The title compound is crystallized from diethyl ether.
