Versuchsvorschrift

268.3 mg (1.51 mmol) of 5-nitroisoquinolin-1(2H)-one is added with 376.5 mg of ammonium chloride and 2.6 ml of water in 14 ml of ethanol and 5.4 ml of tetrahydrofuran. After addition in portions of 1.23 g of zinc powder (heating to 30 to 35° C.), it is stirred for two hours. The reaction mixture is suctioned off through a gas fiber filter and rewashed with ethyl acetate. After the filtrate is washed with water and saturated sodium chloride solution, the organic phase is dried as usual. Filtering off the desiccant and spinning off the solvent produce 196.5 mg (88.1%) of the desired amine.
