To a solution of 2-((E)-4-[4-(5-chloropyridin-2-yl)piperazino]sulfonylbut-3-enyl)-5-fluoropyrimidine and 2-((Z)-4-[4-(5-chloropyridin-2-yl)piperazino]sulfonylbut-3-enyl)-5-fluoropyrimidine (0.44 g), in tetrahydrofuran (5 ml), was added hydroxylamine (1.0 ml, 50% aqueous solution). The mixture was stirred for 18 hours and then diluted with EtOAc (10 ml) and washed with saturated ammonium chloride solution (10 ml). The organic layer was dried over Na2SO4 and evaporated in vacuo to give 2-[4-[4-(5-chloropyridin-2-yl)piperazino]sulfonyl-3-(hydroxyamino)butyl]-5-fluoropyrimidine (0.483 g).
