실험 절차

A microwave reaction vial was charged with 6-bromo-2-chlorobenzo[d]thiazole (300 mg, 1.21 mmol), cyclohexylmethanamine (143 mg, 1.27 mmol), triethylamine (183 mg, 1.81 mmol) and 2.4 mL DMF. The vial was sealed, and the mixture was irradiated in the microwave for 20 min at 150° C. The reaction mixture was concentrated twice from toluene and purified by silica gel chromatography (0-50% 90/10 CH2Cl2/MeOH in CH2Cl2), which provided 6-bromo-N-(cyclohexylmethyl)benzo[d]thiazol-2-amine (240 mg, 61%) as a white solid. MS (ESI pos. ion) m/z calc'd for C14H17BrN2S: 325.3/327.3. found 325.0/327.0.
