実験手順
The process is performed according to the procedure described in Example 1 (step 1.4.). Starting with 1.50 g (3.43 mmol) of 2-(ethyloxy)-2-oxoethyl 4-{5-[3-(trifluoromethyl)phenyl]-2-pyridyl}-1-piperazinecarboxylate, obtained in step 3.4, and 8.6 ml (17.15 mmol) of a solution of methylamine (2M) in tetrahydrofuran, and after chromatography on silica gel, eluting with a 97/3 mixture of dichloromethane and methanol, followed by washing with diisopropyl ether, 1.18 g of product are obtained in the form of a white solid.
