Lithium borohydride → 4-(2-Hydroxy-ethyl)-piperazine-1-sulfonic acid [2-(2,3-difluoro-benzylsulfanyl)-6-methoxy-pyrimidin-4-yl]-amide

Participants

Reaction Steps

The title compound was prepared according to the procedure outlined in example 24 using a mixture of {4-[2-(2,3-Difluoro-benzylsulfanyl)-6-methoxy-pyrimidin-4-ylsulfamoyl]-piperazin-1-yl}-acetic acid ethyl ester (the product from example 86 step i) (0.31 g) lithium borohydride (1M solution in THF) (1.2 mL) in THF (5 mL). Purification was by reverse phase HPLC (symmetry as the stationary phase and NH4OAc/acetonitrile as the mobile phase) then titurated with Toluene, MeOH followed by DCM to give the title compound as a white solid.
