Water → (2S)-2-Methyl-1-{[2-(methyloxy)-3-pyridinyl]carbonyl}-4-{[4-(trifluoromethyl)phenyl]sulfonyl}piperazine

To a solution of (3S)-3-methyl-1-{[4-(trifluoromethyl)phenyl]sulfonyl}piperazine (Description 2) (100 mg, 0.324 mmol) in DMF (5 ml) was added HOBT.H2O (49.7 mg, 0.324 mmol), HBTU (123 mg, 0.324 mmol), 2-(methyloxy)-3-pyridinecarboxylic acid (49.7 mg, 0.324 mmol) and DIPEA (0.170 ml, 0.973 mmol) and the reaction mixture was stirred for 1 h at room temperature. The reaction mixture was reduced in vacuo. The residue was dissolved in DCM (50 ml), transferred to a separating funnel and the solution was washed with NaHCO3 (5 ml), twice. The organic layer was dried with magnesium sulphate which was removed by filtration and the filtrate evaporated to dryness in vacuo. The residual oil was dissolved in 1:1 MeCN/DMSO (1.8 ml) and purified by MDAP in two batches. The fractions containing the desired product were combined and evaporated to dryness in vacuo to yield the title compound (95 mg).
