実験手順

To a solution of (3R)-3-methyl-1-{[4-(trifluoromethyl)phenyl]sulfonyl}piperazine (Description 12) (80 mg, 0.259 mmol) in DMF (4 ml) was added 6-methyl-3-pyridinecarboxylic acid (35.6 mg, 0.259 mmol), HOBT.H2O (39.7 mg, 0.259 mmol), HBTU (98 mg, 0.259 mmol) and DIPEA (0.136 ml, 0.778 mmol) and the reaction mixture was stirred at room temperature for 1 h. The DMF was evaporated in vacuo then 5 ml of DCM were added and washed with saturated NaHCO3 solution (5 ml), dried on a phase separation cartridge and evaporated in vacuo. The crude material was dissolved in MeCN/DMSO 1:1 and purified by MDAP to give the title compound (93 mg).
