Procedure

This compound was prepared by the method outlined for example 5 step 6. Thus 3-(5-iodo-pyridin-2-yloxy)-azetidine-1-carboxylic acid pyridin-3-ylamide (300 mg, 0.76 mmol) was reacted with 3-hydroxyphenylboronic acid (156 mg, 1.14 mmol) to afford a crude product purified by flash chromatography on silica gel eluting with solvent gradient of 1:19 to 1:9 7N ammonia in methanol solution: dichloromethane. This affords the title compound (130 mg, 47%) as a colourless powder.
