Reaction Steps

A mixture of 3-((3-bromopyridin-2-yl)oxy)cyclobutanamine hydrochloride (242 mg, 1 mmol), 2-chloro-benzothiazole (169 mg, 1 mmol) and DIEA (286 mg, 2 mmol) in NMP (10 mL) was heated to 180° C. for 2 hours in microwave. The reaction mixture was added water, extracted with EtOAc (40 mL), washed with brine and dried over Na2SO4. The organic layers were concentrated and purified by column chromatography to give N-(3-((3-bromopyridin-2-yl)oxy)cyclobutyl)benzo[d]thiazol-2-amine (225 mg, 0.6 mmol, yield 60%). ESI-MS (M+1): 376 calc. for C16H14BrN3OS 375.
