反応手順
To the solution of 2-chloro-6-methoxybenzo[d]thiazole (900 mg, 4.5 mmol) in 4.5 ml of NMP was added cyclohexylmethanamine (865 mg, 7.65 mmol) and DIPEA (1.57 ml, 9.0 mmol). The reaction solution was stirred at 105-110° C. for 66 hours. The reaction was worked up by adding 250 ml ethyl acetate and washed with 2×60 ml of saturated NaHCO3, 3×60 ml water, 1×60 ml saturated NaCl, dried with sodium sulfate, filtered and concentrated in vacuo to give N-(cyclohexylmethyl)-6-methoxybenzo[d]thiazol-2-amine as solid (1.18 grams). ES/MS m/z 277.1 (MH+).
