Reaction Steps

To a mixture of N-methoxy-N,2,2,5-tetramethyl-1,3-dioxane5-carboxylic acid amid (1.07 g, 4.92 mmol) and THF (10 mL) was gradually added 3 mol/L methylmagnesium bromide in THF (2.46 mL, 7.4 mmol) at 0° C. under nitrogen atmosphere, and the resulting mixture was stirred at 0° C. for 4 hours. After the reaction was completed, saturated ammonium chloride aqueous solution was added to the reaction mixture and the resulting mixture was extracted with ethyl acetate. The extract was washed with brine, dried over anhydrous sodium sulphate, and concentrated in vacuo to give 1-(2,2,5-trimethyl-1,3-dioxane5-yl)ethanone (0.76 g, yield: 90%) as colorless oil.
