Reaction Steps

To a solution of 2-(4-cyclopropylpiperazin-1-yl)benzooxazole-5-carbonitrile (500 mg, 1.85 mmol) in MeOH-THF (12 mL, 5:3) was added NH4OH (1.5 mL) and Raney Ni (100 mg). The mixture was stirred for 12 h at rt under a H2 atmosphere. After filtration, the mixture was concentrated to give 5-aminomethyl-[2-(4-cyclopropylpiperazin-1-yl)benzooxazole (500 mg, 99%), which was used in the next step without further purification.
