Reaction Steps

3-(4-Chloro-[1,3,5]triazin-2-yl)-2-oxo-2,3-dihydro-benzimidazole-1-carboxylic acid tert-butyl ester was prepared by a process similar to that described by N. A. Meanwell, et al., J. Org Chem., 60,1565-82 (1995). A mixture of 2,4-dichloro-1,3,5-triazine (0.64, 4.26 mmol) and solid K2CO3 (0.6 g, 4.34 mmol) was suspended in AcCN (10 mL) under nitrogen at RT followed by addition of 2,3-dihydro-2-oxo-1H-benzimidazole-1-carboxylic acid, 1,1-dimethylethyl ester (1.0 g, 4.26 mmol). The mixture was stirred at RT for 1.5 h. The mixture was poured onto ice/water and the white solid formed, was collected by suction filtration and dried under vacuum to give 3-(4-chloro-[1,3,5]triazin-2-yl)-2-oxo-2,3-dihydro-benzimidazole-1-carboxylic acid tert-butyl ester.
