Reaction Steps

Using an analogous procedure to that described for the preparation of the starting material in Example 11, tert-butyl (2S)-2-[(4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxyquinazolin-7-yloxy)methyl]pyrrolidine-1-carboxylate (170 mg, 0.33 mmol) was reacted with hydrogen chloride in dioxane. The solid was dissolved in methanol and absorbed onto an Isolute SCX column which was washed through with methanol and then the product was eluted with 7N ammonia in methanol to give 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxy-7-[(2S)-pyrrolidin-2-ylmethoxy]quinazoline (128 mg, 93%).
