Versuchsvorschrift

The title compound was prepared from 3-oxopiperazine-1-sulfonamide (the product of step i) (0.22 g) and 4-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidine (the product of Example 35, step i) (0.25 g) according to the procedure outlined in Example 1, step iv). The crude material was purified by column chromatography using EtOAc/isohexane (1:1) as eluent to give a white solid. This solid was dissolved in EtOAc and Et2O and extracted with 1N sodium hydroxide. The basic solution was washed with Et2O, acidified with dilute hydrochloric acid and extracted with EtOAc. The organic solution was washed with H2O, dried (MgSO4) and the solvent evaporated in vacuo to give the product as a yellow foam.
