The present invention relates to chemical processes for the manufacture of certain quinazoline derivatives, or pharmaceutically acceptable salts thereof. The invention also relates to processes for the manufacture of certain intermediates useful in the manufacture of the quinazoline derivatives and to processes for the manufacture of the quinazoline derivatives utilising said intermediates. In particular, the present invention relates to chemical processes and intermediates useful in the manufacture of the compound 4-[(4-fluoro-2-methy-1-1H-indol-5-yl)oxy]-6-methoxy-7-[3-(pyrrolidin-1-yl)propoxy]quinazoline starting from a compound of Formula IX:
wherein R4 is a protecting group; or an intermediate there between, using process steps, reagents and conditions as described.

The final synthetic step in the synthesis of cediranib, AZD2171, 1, is the alkylation of a phenol with an alkyl halide to generate an ether. Our need to understand and control the formation of synthetic impurities generated in this step of the synthesis led us to investigate the kinetics and mechanism of the alkylation of indolphenol, 2, 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxyquinazolin-7-ol
