Reaction Steps

To a solution of 4-hydroxy-3,3-dimethylbutan-2-one (9.7 g, 84 mmol) and DIPEA (16.04 mL, 92 mmol) in DCM (50 mL) cooled to 0° C. was dropwise added methanesulfonyl chloride (7.16 mL, 92 mmol). The reaction mixture was stirred at rt for 18 h. The reaction mixture was diluted with EtOAc and washed with sat. NaHCO3, sat. NaCl, dried (MgSO4), filtered and concentrated to yield 2,2-dimethyl-3-oxobutyl methanesulfonate (14.6 g). 1H NMR (400 MHz, CDCl3) δ ppm 4.21 (2H, s), 3.04 (3H, s), 2.21 (3H, s), 1.25 (6H, s).
