PROCEDURE
实验过程
In an inert atmosphere, 1-ethyl-3-methyl-4-[2-(4-trifluoromethyl-phenyl)-ethyl]-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine (51 mg, 0.15 mmol) was dissolved in 3-methyl-2-butyl-ketone (MIBK) (1 ml) followed by the addition of DIPEA (21.3 mg, 0.165 mmol) and toluene-4-sulfonic acid methylcarbamoyl-phenyl-methyl ester (71.8 mg, 0.225 mmol). The reaction mixture was heated to 90° C. for 24 h, concentrated in vacuo and the crude product was purified by prep. HPLC to give 70 mg (95%) of 2-{1-ethyl-3-methyl-4-[2-(4-trifluoromethyl-phenyl)-ethyl]-1,4,6,7-tetrahydro-pyrazolo[4,3-c]pyridin-5-yl}-N-methyl-2-phenyl-acetamide. LC-MS: tR=0.84 min; [M+H]+=485.28.
