反应详情

A mixture of 4-chloro-2,6-di-1-pyrrolidinyl-pyrimidine (II, J. Med. Chem., 33, 1145 (1990), 300 g) in ethanolamine (1000 mL) is heated at 140° for 66 hr. The reaction mixture is cooled, diluted with water (1700 mL) and the product is isolated by filtration, to give the title compound, mp=150.5-151.50°; NMR (CDCl3) 6.55, 4.83, 4.75, 3.75-3.72, 3.54-3.38 and 1.93-1.85 δ.
