실험 절차

A mixture of 2-(1,1-dioxo-1λ6-[1,2]thiazinan-2-yl)-5-hydroxy-1-methyl-6-oxo-1,6-dihydro-pyrimidine-4-carboxylic acid ethyl ester (1.00 g, 3.02 mmol) and 4-fluorobenzylamine (1.31 g, 10.5 mmol) in a mixture of anhydrous ethyl alcohol (40 ml) and N,N-dimethylformamide (10 ml) was heated under reflux for 10 h. The solvent was then evaporated in vacuo and the residue was diluted with dichloromethane (500 ml). The organic phase was washed with 5% aqueous acetic acid, brine and dried over anhydrous sodium sulfate. Evaporation of the solvent and recrystallization of the white solid obtained from dichloromethane and ethanol gave 1.04 g (84% yield) of the title amide as white crystals; mp 227–228° C. 1HNMR 400 MHz (CDCl3) δ (ppm): 1.75 and 2.07 (2×1H, m, CH2), 2.28–2.43 (2H, m, CH2), 3.19–3.31 (2H, m, CH2), 3.64 (3H, s, NCH3), 3.6–3.8 (2H, m, CH2), 4.59 (2H, AB part of ABX system, JAB=14.9 Hz, Δν=36.1 Hz, JAX=6.6 Hz, JBX=5.8 Hz, NCH2), 7.06 (2H, m, aromatics), 7.31 (2H, m, aromatics), 7.52 (1H, broad NH). Anal. Calcd for C17H19FN4O5S: C 49.75, H 4.67, N 13.65. Found: C 49.67, H 4.63, N 13.77.
