실험 절차

To a solution of (2S)-2-methyl-1-{[4-(trifluoromethyl)phenyl]sulfonyl}piperazine hydrochloride (Description 8) (100 mg, 0.270 mmol) in THF (5 ml) was added HOBT.H2O (41.3 mg, 0.270 mmol), HBTU (102 mg, 0.270 mmol) and 6-methyl-3-pyridinecarboxylic acid (40.7 mg, 0.297 mmol). The mixture was stirred for 5 min before addition of DIPEA (0.118 ml, 0.674 mmol) and the resultant solution stirred at room temperature for 16 h. The mixture was then concentrated and the residue partitioned between DCM (10 ml) and water (10 ml), the layers were separated using a hydrophobic frit, the organic layers were then concentrated to dryness and the crude material dissolved in DMSO and purified by MDAP giving the title compound (100.2 mg) as a colourless oil which solidified on standing.
