実験手順

A mixture of 0.05 mmol 2-isopropoxy-5-methanesulfonyl-benzoic acid (Compound 1.2), 0.06 mmol 1-(2-fluoro-4-trifluoromethyl-phenyl)-piperazine, 0.055 mmol TBTU and 0.25 mmol DIPEA in 1 ml DMF was stirred at RT for 16 h. 0.5 ml MeOH/HCOOH 1/1 was added and the mixture was subjected to reversed phase preparative HPLC separation eluting with an acetonitrile/water gradient yielding the title compound. MS (m/e): 489.2 (MH+, 100%)
