Isobutyryl chloride → HCID 58960252, compound

Participants

Reaction Steps

Using an analogous procedure to that described for the preparation of Example 19, 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxy-7-[(2S)-pyrrolidin-2-ylmethoxy]quinazoline (150 mg, 0.36 mmol), (prepared as described for the starting material in Example 12), was reacted with isobutyryl chloride (45 μl, 0.43 mmol). The product was purified by column chromatography, eluting with methanol/methylene chloride (2/98) to give 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-7-{[(2S)-1-isobutyrylpyrrolidin-2-yl]methoxy}-6-methoxyquinazoline (95 mg, 54%).
