Participants

Reaction Steps

A stirred solution of 3-(5,6-dimethyl-1H-benzoimidazol-2-yl)-1H-pyrazol-4-ylamine [100 mg, Example 233(c)] and diisopropylethylamine (307 μl) in dichloromethane (10 ml) was treated with chloroacetyl chloride (105 μl). The reaction mixture was stirred for 30 minutes at room temperature, then treated with morpholine (575 μl), then kept at room temperature overnight and then evaporated. The oily residue was partitioned between ethyl acetate and water and the organic phase was washed with water, then dried over magnesium sulfate and then evaporated. The residue was subjected to flash chromatography on silica eluting with ethyl acetate to give the N-[3-(5,6-dimethyl-1H-benzoimidazol-2-yl)-1H-pyrazol-4-yl]-2-morpholin-4-yl-acetamide (49.9 mg) as an off-white solid. MS: 355.68 (M+H)+. HPLC (METHOD B1): RT=8.28 minutes. (b) 2-Dimethylamino-N-[3-(5,6-dimethyl-1H-benzoimidazol-2-yl)-1H-pyrazol-4-yl]-acetamide
