Reaction Steps

A mixture of methyl 2,2-dimethyl-3-hydroxypropionate (100 g, 0.76 mol), 4-toluenesulfonyl chloride (151 g, 0.80 mol), 4-dimethylaminopyridine (4.6 g, 0.038 mol), and pyridine (200 mL) was stirred for 20 hrs and then was diluted with 200 mL toluene, stirred for 30 min, and filtered. The filtrate was concentrated to 250 mL under reduced pressure, diluted with 100 mL toluene, filtered, and concentrated. The residue was suspended in 200 mL hexanes, and the solvent was removed under reduced pressure to yield the title compound, desired product (235 g, 100%) contaminated by a trace of 4-toluenesulfonyl chloride.
