Diisopropylethylamine → Morpholine-4-carboxylic acid [1-(1-carbamimidoyl-4-cyano-piperidin-4-ylcarbamoyl)-2-cyclohexyl-ethyl]-amide p-toluenesulfonate

Participants

Reaction Steps

Morpholine-4-carboxylic acid [1-(4-cyano-piperidin-4-ylcarbamoyl)-2-cyclohexyl-ethyl]-amide hydrochloride (0.2 g, 0.47 mmol) was dissolved in 3 mL of DMF and 2 equiv of Hunig's base was added followed by 1-carbamimidoyl-1,2,3-benztriazole p-toluenesulfonate (0.16 g, 0.47 mmol). The reaction was stirred 24 hours at which time the solvent was removed in vacuo. The resulting paste was purified by preparative HPLC to give the title compound; MS, m/z 434, M+1-p-toluene sulfonate).
