The mixture was stirred and heated to 100° C. The reaction was held at 100° C.±1° C. for 90 minutes and then cooled to room temperature. The reaction mixture was diluted with water (100 milliliters) and methyl t-butyl ether, washed several times with water until neutral pH, dried over sodium sulfate and concentrated to furnish 34.4 grams of crude product. After distillation by Kugelruhr 23.4 g of the product, 76% yield, were obtained and confirmed by 1H NMR.
