Procedure

A mixture of 7-hydrazino-3,4-dihydro-2H-isoquinolin-1-one (8.0 g, 37.6 mmol) and 4,4-dimethyl-3-oxo-pentanenitrile (5.64 g, 45 mmol) in EtOH (100 mL) and conc. HCl (10 mL) was heated at reflux overnight. After removal of the solvent, the residue was washed with ether to afford 7-(5-amino-3-t-butyl-pyrazol-1-yl)-3,4-dihydro-2H-isoquinolin-1-one hydrochloride as a yellow solid (11.5 g, 96% yield), which was used without further purification.
