実験手順
3-fluoro-4-[tetrahydro-1,1-dioxido-2-(2-propenyl)-2H-1,2-thiazin-4-yl]benzenamine (1.154 g, 4.06 mmol) is dissolved in THF (15 ml) to which is added benzyl chloroformate (765 mg, 4.48 mmol) followed by a solution of sodium bicarbonate (700 mg, 8.33 mmol) in water (10 ml). After stirring for 2 hr most of the THF is evaporated and the residue is extracted with ethyl acetate (100 ml). After washing with water (25 ml) and brine, the solution is dried (MgSO4) and evaporated to afford the title compound as white crystals (1.70 g, 100%) mp 138-140°.
