Procedure
To freshly fused zinc chloride (27.3 mg) and trimethylacetylchloride (5.11 ml, 41.5 mmol) in methylene chloride(10 ml) at 10° C. was added isobutyraldehyde (freshly distilled) (3.77 ml, 41.5 mmol) dropwise, maintaining the temperature at <25° C. Once the addition was complete, the reaction was stirred for one hour at room temperature. The reaction mixture was then washed with 20% NaOAc, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the title A compound (3.25 g) as a clear liquid.
