Reaction Steps
To a solution of 2-amino-4-(morpholin-4-yl)benzonitrile 3.65 g (18.0 mmol) in ethylenediamine 20 mL was added phosphorus pentasulfide 4.00 mg (0.018 mmol) and stirred at 140° C. for 16 hours. After cooling to room temperature, the solvent was evaporated. The residue was washed with water and diethyl ether to give the title compound 3.70 g as off-white solid. Yield 83.5%.
