Participants

Reaction Steps

By proceeding in a manner similar to Example 235(a) above but using 3-formyl-pyrazole-4-carboxylic acid-isopropylamide [198 mg, Reference Example 60)] and 4-methoxy-5-methyl-benzene-1,2-diamine [166 mg, Reference Example 29(b)] and subjecting the reaction product to flash chromatography on silica eluting with dichloromethane/methanol (95:5) followed by recrystallisation from a mixture of ethyl acetate and n-pentane there was prepared 3-(5-methoxy-6-methyl-1H-benzoimidazol-2-yl)-1H-pyrazole-4-carboxylic acid isopropylamide (145 mg) as a white solid. LC-MS (Method H): RT=2.09 minutes, 314.27 (M+H)+, 312.29 (M−H)−.
