Reaction Steps

To a solution of {1-[6-(1H-Indazol-6-ylcarbamoyl)-2-(2-trifluoromethyl-phenylamino)-3H-benzoimidazol-5-yl]-piperidin-4-yl}-carbamic acid tert-butyl ester (0.25 mmol; see Example 155) in methanol (1 mL) was 4M HCl in dioxane (0.5 mL) added. The resulting mixture was stirred at room temperature for 5-6 h. The volatiles were removed in vacuo, and the residue obtained was suspended in ether. The solid obtained was collected by filtration, washed with ether and dried in vacuo to afford 6-(4-Amino-piperidin-1-yl)-2-(2-trifluoromethyl-phenylamino)-1H-benzoimidazole-5-carboxylic acid (1H-indazol-6-yl)-amide as a hydrochloride salt. MS: m/z 535 (M+H)+.
