Reaction Steps

2-[2-(2-benzyl-5-methyl-2H-pyrazol-3-yl)-ethyl]-isoindole-1,3-dione (80 mg, 0.233 mmol) was dissolved in ethanol (2 ml) followed by the addition of an 1M solution of hydrazine in methanol (0.34 ml, 0.34 mmol). The reaction mixture was stirred at 90° C. for 16 h, cooled to rt and DCM (3 ml) was added and the suspension was filtered. The filtrate was concentrated under reduced pressure to give 40 mg (80%) 2-(2-benzyl-5-methyl-2H-pyrazol-3-yl)-ethylamine. LC-MS: tR=0.58 min; [M+H]+=216.38.
