Versuchsvorschrift

A mixture of 2-methoxy-5-(5-trifluoromethyl-pyridin-2-yloxy)-pyridine (0.28 g, 1.04 mmol) and pyridine hydrochloride (1.00 g, 8.65 mmol) was heated in a kugelrohr oven at 200° C. for 10 minutes. After cooling to room temperature, the reaction mixture is dissolved in dichloromethane and extracted with water, dried over sodium sulphate, filtered and evaporated in vacuo, yielding the title compound (180 mg, 68% yield) as a white solid.
