实验步骤: In a similar manner, 2-methylsulfonyl-4-(ethoxycarbonylmethyl)amino-5-nitro-6-(2-benzyloxy-5-cyanophenoxy)pyrimidine, a compound of formula (M), prepared as described below in Preparation 4, is treated with 3-(dimethylaminocarbonyl)phenol, a compound of formula (B) to afford 2-(3-dimethylaminocarbonylphenoxy)-4-(ethoxycarbonylmethyl)amino-5-nitro-6-(2-benzyloxy-5-cyanophenoxy)pyrimidine, a compound of formula (N). as described below in Preparation 4

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To 2-methylthio-4,6-dichloro-5-nitropyrimidine, a compound of formula (A), (5.0 g, 20.8 mmol) in 200 mL acetonitrile at 0° C. was added cesium carbonate (8.82 g, 27.1 mmol) followed by the addition of 3-(dimethylaminocarbonyl)phenol (3.44 g, 20.8 mmol), a compound of formula (B), and the reaction mixture was stirred for 16 hours. The volatiles were evaporated and the residue chromatographed on silica gel (CH2 Cl2 /ethyl acetate, 7:12) to afford 6.3 g (83% yield) of 2-methylthio-4-chloro-5-nitro-6-(3-(dimethylaminocarbonyl)phenoxy)pyrimidine, a compound of formula (C). The volatiles were evaporated the residue chromatographed on silica gel (CH2 Cl2 /ethyl acetate, 7:12)
