Procedure

(3RS)-3-Hydroxy-2,2-dimethyl-succinic acid [Tetrahedron Letters (2002), 43(52), 9513-9515] (120 mg, 0.74 mmol) was suspended in CH2Cl2 (2 ml) and cooled to 0-5° C. Trifluoroacetic anhydride (260 μl, 1.85 mmol) was added and the reaction mixture stirred for 2 hours at room temperature. The reaction mixture was evaporated to dryness and used without any further purification in the next step.
