Reaction Steps

4-(5-Bromopyridin-2-yl)tetrahydro-2H-pyran-4-carbonitrile (2 g) described in Reference Example 87 in concentrated hydrochloric acid (10 ml) was stirred at 100° C. for 3 days. After completion of the reaction, a saturated aqueous solution of potassium carbonate was added to alkalify the mixture, and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was evaporated to give the titled compound (1.05 g) as a white solid.
