Reaction Steps

A solution of cyclopropanecarboxylic acid [3-(6-ethoxy-5-fluoro-1H-benzimidazol-2-yl)-1-(tetrahydropyran-2-yl)-1H-pyrazol-4-yl]amide [90 mg, Reference Example 48(d)] in a 1/1 mixture of trifluoroacetic acid and dichloromethane (30 mL) was stirred for 5 hours and then evaporated. The residue was mixed with ethyl acetate (30 mL) and aqueous sodium bicarbonate (30 mL). The organic layer was evaporated to give cyclopropanecarboxylic acid [3-(6-ethoxy-5-fluoro-1H-benzimidazol-2-yl)-1H-pyrazol-4-yl]amide (44 mg). LC-MS (Method E): RT=2.34 minutes, 330 (M+H)+.
