Reaction Steps

A mixture of 5-chloro-2-nitroaniline (5.6 g, 32 mmol), thiomorpholine (10.0 g, 97 mmol) and anhydrous potassium carbonate (4.98 g, 36 mmol) in N,N-dimethylacetamide (10 ml) was stirred at 135° C. under nitrogen for 1 day. Sample NMR analysis showed complete conversion of the starting material. The resultant mixture was then cooled to room temperature, poured into cold water and stirred vigorously for 3 hours. The resulting brown precipitate was collected by filtration, washed well with water then dried on the filter funnel. The resulting brown solid was washed with diethyl ether, filtered, washed with additional diethyl ether, dried to afford 2-Nitro-5-thiomorpholin-4-yl-phenylamine (7.0 g, 91.5%) as a brown powder, and used in the next step without further purification.
