Procedure

Morpholine (9.5 mL, 108 mmol)) was added to a solution of cyanuric chloride (20 g, 108 mmol) in chloroform (10 mL) and stirred at −5° C. for 1 hour. Reaction mixture was diluted with water, extracted with dichloromethane. The organic layer was dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. Crude product was purified by silica gel (100-200 mesh) column chromatography using 5% ethyl acetate in pet-ether as an eluent to give 4-(4,6-dichloro-1,3,5-triazin-2-yl)morpholine (10 g, 39% yield).
