Reaction Steps

The subtitle compound was prepared by adding 60% sodium hydride (0.18 g) portionwise to a solution of N-[2-[[(2,3-Difluorophenyl)methyl]thio]-6-methoxypyrimidin-4-yl]piperazine-1-sulfonamide, trifluoroacetate salt (the product from example 36) (0.53 g) and ethyl 2-bromoacetate (0.36 mL) in THF (10 mL). The reaction mixture was diluted with H2O and extracted with EtOAc. The organic layer was washed with brine and evaporated to give the subtitle compound as an oil.
