Reaction Conditions

Reaction Steps

To the solution of 5-fluoro-6-methoxybenzo[d]thiazol-2-amine (350 mg, 1.76 mmol, 1.0 eq) in 2 mL of NMP was added bromomethyl cyclohexane (370 μL, 2.65 mmol, 1.5 eq) and potassium carbonate (366 mg, 2.65 mmol, 1.5 eq) at room temperature. The reaction mixture was stirred at 80° C. for 24 hours with subsequent addition of reagents till reaction completion and thereafter quenched with saturated sodium bicarbonate solution (100 mL) which was then extracted with ethyl acetate (125 mL×3), combined organic layers dried over sodium sulfate, filtered and condensed under reduced pressure. Purification of the crude over ISCO using slow gradient of 0%-50% ethyl acetate-hexane gave 310 mg of product in 60% yield. LC/MS (m/z) [295.1] (MH+)
