실험 절차

A mixture of 2-(1,1-dioxo-1λ6-[1,2]thiazinan-2-yl)-5-methoxy-1-methyl-6-oxo-1,6-dihydro-pyrimidine-4-carboxylic acid 4-fluoro-benzylamide (0.115 g, 0.27 mmol) in 2,4,6-collidine (3 ml) was treated with lithium iodide (0.060 g) and the resulting mixture was heated at 120° C. for 30 min. The collidine was then evaporated in vacuo, the residue was diluted with a small volume of water and the pH was adjusted to a value of 7 with 0.1 N hydrochloric acid. The aqueous phase was extracted three times with dichloromethane and the combined organic extracts were washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by chromatography on reversed phase silica gel (Waters, C-18, 125 A, elution with water-acetonitrile 7:3 to 6:4) to give 0.058 g (52% yield) of the title amide as a white solid; mp 226–227° C. (dichloromethane-ethanol).
