p-Toluenesulfonic acid monohydrate → N-hydroxy-N'-methyl-2-[methyl({4'-[3-(morpholin-4-yl)propoxy]biphenyl-4-yl}carbonyl)amino]propanediamide 4-methylbenzenesulfonate

Participants

Reaction Steps

To a THF (1.0 mL) suspension of N-hydroxy-N′-methyl-2-[methyl({4′-[3-(morpholin-4-yl)propoxy]biphenyl-4-yl}carbonyl)amino]propanediamide (Compound 7, 24 mg) as obtained in Example 4-(5), p-TsOH.H2O (9.5 mg) was added, and the mixture was stirred for 10 minutes at room temperature. The precipitate was collected by filtration to obtain N-hydroxy-N′-methyl-2-[methyl({4′-[3-(morpholin-4-yl)propoxy]biphenyl-4-yl}carbonyl)amino]propanediamide 4-methylbenzenesulfonate (Compound 7b, white solid) (26 mg, 79%).
