Procedure
The subtitle compound was prepared from 1,1-dimethylethyl 4-sulfamoylpiperazine-1-carboxylate (the product of example 15, 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 on silica gel using EtOAc/isohexane (2:8) as eluent. Yield: 0.36 g
