Reaction Steps

NaOAc (3.66 g, 44.5 mmol) was added to an EtOH (100 mL) solution of 1-methyl-2,2,4-trioxo-1,2,3,4-tetrahydro-2λ6-benzo[c][1,2]thiazine-7-carboxylic acid methyl ester (4.00 g, 14.8 mmol) and hydroxylamine hydrochloride (1.55 g, 22.3 mmol). After heating at reflux for 4 days, it was evaporated, diluted with CH2Cl2 (400 mL), washed with H2O, dried over MgSO4, filtered, and concentrated in vacuo. Crystallization from MeOH provided the title compound. MS (−APCI, m/z): 283 (M−H)−.
