Procedure

In a dry and nitrogen purged 5 L round bottom flask equipped with a mechanical stirrer, D(−) tartaric acid (129 g, 0.86 mol) was added to the product from step C (243 g, 0.78 mol) in acetone/water (9:1, 2430 mL) at about 17° C. The mixture was stirred at room temperature overnight, filtered, the solid was collected and washed with cold acetone and dried under vacuum. The product was obtained as a yellow solid (284 g, yield 78.8%).
