7-(2-Morpholin-4-yl-ethoxy)-2-(4-nitrophenyl)imidazo[2,1-b]benzothiazole was dissolved into methanol and THF and placed in a hydrogenator. Raney nickel was added and the vessel was pressurized with hydrogen and stirred for >24 hours. The reaction mixture was concentrated to a thick paste and diluted with methyl tert-butyl ether. The resulting solids were filtered and washed with methyl tert-butyl ether and dried under vacuum to give 7-(2-morpholin-4-yl-ethoxy)-2-(4-aminophenyl) imidazo[2,1-b]benzothiazole.
