Versuchsvorschrift

To a solution of 1-{[4-(trifluoromethyl)phenyl]sulfonyl}piperazine (Description 1) (100 mg, 0.340 mmol) in DMF (5 ml) was added HOBT.H2O (52.0 mg, 0.340 mmol), HBTU (129 mg, 0.340 mmol), 6-methyl-3-pyridinecarboxylic acid (46.6 mg, 0.340 mmol) and DIPEA (0.18 ml, 1.02 mmol). The reaction mixture was stirred for 2 h at room temperature. Reaction mixture was transferred to a 100 ml round bottom flask and was reduced to dryness in vacuo. The residue was dissolved in DCM (50 ml) and was transferred to a separating funnel then washed with saturated NaHCO3 solution (5 ml), twice. The organic layer was collected and dried with dried magnesium sulphate. The solid was removed by filtration and the filtrate collected in a 250 ml round bottom flask and reduced to dryness in vacuo. The residue was then dissolved in 1.8 ml 1:1 MeCN/DMSO and purified by MDAP in 2 batches. The fractions containing desired product were combined in a 250 ml round bottom flask and reduced in vacuo to yield the title compound (69 mg).
