Reaction Steps

[5-Amino-1-(2-methyl-1H-benzimidazol-5-yl)-1H-pyrazol-4-yl]-(1-benzenesulfonyl-6-morpholin-4-ylmethyl-1H-indol-2-yl)-methanone (132 mg, 0.22 mmol) was dissolved in tetrahydrofuran (THF) (1.0 ml), and then a tetrahydrofuran (THF) solution of 1 M tetrabutylammonium fluoride (0.46 ml, 0.46 mmol) was added thereto. The mixture was heated at 65° C. with stirring for 22 hours. The reaction mixture was then cooled to room temperature, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (dichloromethane/methanol=100/10) to give [5-amino-1-(2-methyl-1H-benzimidazol-5-yl)-1H-pyrazol-4-yl]-(6-morpholin-4-ylmethyl-1H-indol-2-yl)-methanone as a yellow solid (74 mg, 75%).
