Procedure

N-(6-Methoxy-pyridin-3-yl)-benzamide (2.38 g, 10.4 mmol) was dissolved in a mixture of tetrahydrofuran and diethyl ether. HCl-gas was bubbled into the solution for 5 minutes. More diethyl ether was added and the white precipitate was collected by suction, washed twice with diethyl ether and heated in a kugelrohr apparatus at 180° C. for 0.5 hours. The solid material was crystallised from methanol:water, washed twice with water and dried overnight in a vacuum oven, yielding the title compound (1.19 g, 53% yield) as a grey solid.
