Procedure

To a solution of 3-(4-methoxybenzyl)-6,7,8,9-tetrahydro-3H-pyrazolo[3,4-c]isoquinoline-7-carboxylic acid (0.072 g, 0.21 mmol), diisopropylethylamine (0.1 mL), aniline (23 μl, 0.21 mmol) in dimethylformamide (5 mL) was added HBTU (0.121 g). The mixture was stirred at room temperature for 24 hours, poured into ethyl acetate (100 mL) and washed with water (200 mL). The organic layer was dried with anhydrous magnesium sulfate and evaporated to dryness to give crude 3-(4-methoxybenzyl)-N-phenyl-6,7,8,9-tetrahydro-3H-pyrazolo[3,4-c]isoquinoline-7-carboxamide as a brown oil, which was used in the next step without any further purification. LCMS [M+H]: 413.
