Reaction Steps
A solution of (S)-(Z)-3-[(4-acetyl-1H-pyrrol-2-yl)methylene]-1,3-dihydro-5-fluoro-4-[(pyrrolidin-2-yl)ethynyl]-2H-indol-2-one (25 mg, 0.07 mmol) (Example 109 above) in dioxane (3 mL) was treated with aqueous HCl under vigorous stirring. (S)-(Z)-3-[(4-Acetyl-1H-pyrrol-2-yl)methylene]-1,3-dihydro-5-fluoro-4-[(pyrrolidin-2-yl)ethynyl]-2H-indol-2-one hydrochloride salt was obtained upon lyophilization of this solution. (Yield 24 mg, 76%).
