Reaction Steps

To 1.09 g of 2,2-dimethyl-5-(pyridin-3-yl)-1,3-dioxane-5-carboxylic acid were added 20 ml of toluene, 0.9 ml of triethylamine, 2.4 ml of benzyl alcohol, and 1.3 ml of diphenylphosphoryl azide, followed by stirring at 100° C. for 17 hours. After leaving to be cooled, to the reaction mixture were added a saturated aqueous sodium hydrogen carbonate solution and ethyl acetate to carry out a layer separation operation. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to obtain 1.01 g of benzyl[2,2-dimethyl-5-(pyridin-3-yl)-1,3-dioxan-5-yl]carbamate.
