실험 절차

A solution of 28 mg (0.12 mmol) of 6-Bromo-pyrazolo[1,5-a]pyrimidine-2-carboxylic acid, 19 mg (0.13 mmol) of 1-methyl-1,2,3,4-tetrahydro-isoquinoline, 23 mg (0.12 mmol) of EDC and 19 mg (0.12 mmol) of HOBt in 2 mL of DMF is stirred at room temperature for 24 h. The mixture is concentrated in vacuo and the solid residue is partitioned between methylene chloride (3 mL) and saturated aqueous sodium hydrocarbonate solution (3 mL). The organic layer is separated, washed with 0.5 N HCl, water and brine and concentrated in vacuo. Purification of the residue by flash column chromatography (chloroform:methanol 99:1) gives 26 mg (58%) of title compound as a crystalline solid.
