Reaction Steps

To a solution of N-{1-[(2-chloro-4-hydroxyphenyl)methyl]-1H-pyrazol-3-yl}-2,6-difluorobenzamide (for a preparation see Example 31)(30 mg, 0.082 mmol) in acetonitrile (0.5 ml) was added potassium t-butoxide (9.4 mg, 0.084 mmol) and then 7-bromo-1-heptanol (0.015 ml, 0.099 mmol, Aldrich). The reaction vessel was sealed and heated in a Biotage Initiator microwave to 100° C. for 15 min. After cooling the reaction was diluted with DMSO (0.5 ml) and purified by MDAP on Sunfire C18 column using Acetonitrile-Water with a Formic acid modifier (Method B). The solvent was evaporated in vacuo to give the title compound as a colourless gum (6.7 mg);
