Reaction Steps

To the solution of 2-chloro-6-methoxybenzo[d]thiazole (2.0 g, 10 mmol) in 10 ml of NMP was added (S)-1-cyclohexylethanamine (2.3 g, 18 mmol) and DIPEA (3.5 ml, 20 mmol). The reaction solution was stirred at 110° C. for 96 hr. The reaction was worked up by adding 170 ml ethyl acetate and washed with 1×60 ml of saturated NaHCO3, 1×60 ml 5% NaHCO3 solution, 1×60 ml water, 1×60 ml saturated NaCl, dried with sodium sulfate, filtered and concentrated in vacuo to give (S)—N-(1-cyclohexylethyl)-6-methoxybenzo[d]thiazol-2-amine as crude solid (3.39 grams). ES/MS m/z 291.1 (MH+).
