Versuchsvorschrift

Prepared according to Preparation 48 using 3-difluoromethoxy-2-bromopyridine (Preparation 217) and cyclopropylboronic acid. The reaction was heated to 95° C. for 18 hours before cooling to room temperature and filtering through arbocel. The filtrate was concentrated in vacuo and purified using silica gel column chromatography eluting with ethylacetate:heptane 1:5 to furnish the title compound as a colourless oil (273 mg, 58%).
