该中间体在本合成路线中的序号：(I)The sulfonation of 1-phenyl-1-butene (I) with sulfuryl chloride in hot DMF provided sulfonyl chloride (II), which was then treated with ammonium hydroxyde to give sulfonamide (III). Coupling of the known dichloro bipyrimidinyl derivative (IV) with the sodium salt of sulfonamide (III) yielded the N-pyrimidinyl sulfonamide (V). The remaining chloride was then displaced with sodium methoxide in DMF, and the resultant sulfonamide was finally converted to the potassium salt with ethanolic KOH.
