Methanesulfonyl chloride → HCID 10311308, compound

Participants

Reaction Steps

Using an analogous procedure to that described for the preparation of Example 22, 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxy-7-[(2R)-pyrrolidin-2-ylmethoxy]quinazoline (160 mg, 0.38 mmol), (prepared as described for the starting material in Example 13), was reacted with methanesulphonyl chloride (35 μl, 0.45 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]-6-methoxy-7-{[(2R)-1-(methylsulfonyl)pyrrolidin-2-yl]methoxy}quinazoline (108 mg, 57%).
