To a solution of 2-[6-(1H-indazol-6-ylcarbamoyl)-1H-benzimidazol-2-ylamino]-6,7-dihydro-4H-thiazolo[5,4-c]pyridine-5-carboxylic acid tert-butyl ester (0.25 mmol; see Example 79) in methanol (1 mL), 4M HCl in dioxane (0.5 mL) was added. The resulting mixture was stirred at room temperature for 5-6 h. The volatiles were removed in vacuo, the residue obtained was suspended in ether. The solid obtained was collected by filtration, washed with ether and dried in vacuo to afford 2-(4,5,6,7-tetrahydro-thiazolo[5,4-c]pyridin-2-ylamino)-3H-benzimidazole-5-carboxylic acid (1H-indazol-6-yl)-amide as a hydrochloride salt. MS: m/z 431 (M+H)+.
