実験手順

A solution of 3-chloro-4-fluorobenzenesulfonamide (1.0 g), tert-butyl 2-(aminomethyl)morpholine-4-carboxylate (1.135 g) and N-ethyl-N-isopropylpropan-2-amine (1.246 mL) in dimethylsulfoxide (15 mL) was stirred at 115° C. for 72 hours. The mixture was concentrated, and the residue was purified on a silica gel column eluting with 60% ethyl acetate to provide the title compound.
