PROCEDURE
实验过程
DIEA and cyclopentyl-acetyl chloride are added at 0° to a mixture of 75 mg of 2-(3,5-bis-trifluoromethyl-benzenesulfonylamino)-4,5,6,7-tetrahydro-thiazolo[5,4-c]pyridin-5-ium hydrochloride salt in CH2Cl2. The mixture obtained is stirred at RT for 4 hours, 2 ml of 1 M aqueous NaHSO4 solution are added and two phases formed are separated. The organic layer obtained is concentrated and subjected to preparative HPLC (RP-18). N-[5-(2-Cyclo-pentyl-acetyl)-4,5,6,7-tetrahydro-thiazolo[5,4-c]pyridin-2-yl]-3,5-bis-trifluoromethyl-benzene-sulfonamide is obtained.
