Reaction Conditions

Reaction Steps

To a cooled (0° C.) solution of 4-bromo-1-H-imidazole (0.8 g, 4.0 mmol) in anhydrous DMF (5.0 mmol) was added NaH (60% dispersion in mineral oil, 0.176 g, 4.4 mmol) in a portionwise fashion over 10 minutes. When gas evolution had ceased, 4-(2-Chloro-pyrimidin-4-yl)-morpholine (21)(0.79 g, 4.00 mmol) was added and the mixture heated under the influence of microwave radiation (120° C., 14 min, fixed hold time, pre-stirring 10 seconds, high absorption setting). Water (14 ml) was added to the reaction mixture which caused a precipitate to form. The precipitate was removed by filtration, washed with water (10 ml) and dried in a desiccator to give the title compound (1.17 g, 94.4%) in suitably clean form to be used without any further purification. m/z (LC-MS, ESP): 310 [M+H]+, R/T=3.79 mins
