2-piperazin-1-yl-benzoic acid sulfuric acid salt (˜10 mmol) was suspended in 50 mL of tetrahydrofuran. Then 100 mL of 1.0 M borane in tetrahydrofuran (100 mmol) was added and the reaction was stirred at room temperature overnight with a bubbler attached to release pressure in the flask. The reaction mixture was diluted with 50 mL of methanol. The reduced product (470 mg) crystallized out of the mixture during evaporation.
