Procedure

To (4-(2,2-dimethyl-1,3-dioxan-5-yl)methoxy-3,5-dimethylpyridin-2-yl)methanol monohydrate (690 g), toluene was added to perform azeotropic dehydration (2.1 L×5, 1.75 L×1). To the concentrated product obtained, toluene (393 mL) was added to obtain a toluene solution (921 g) of (4-(2,2-dimethyl-1,3-dioxan-5-yl)methoxy-3,5-dimethylpyridin-2-yl)methanol.
