실험 절차

A mixture of temozolomide (3 g, 15.5 mmol) and Belleau's reagent (4.49 g, 8.5 mmol) was refluxed in DCM (80 mL) overnight. The reaction was quenched with water and the precipitate was filtered and washed with diethyl ether to give the pure title compound as an orange solid. (2.75 g, 84%). δH, (DMSO-d6): 9.92 (1H, s), 9.45 (1H, s), 8.81 (1H, s), 3.85 (3H, s).
