실험 절차

4-Fluorophenyl 2-[4-[2-(1-pyrrolidinyl)ethoxy]phenyl)benzo[b]thiophen-3-yl ketone (Example 145, Part A) (1.1 g; 2.5 mmol) was combined with 1.6 mL (12.3 mmol) of 1-(2-aminoethyl)pyrrolidine and 1.0 g (7.4 mmol) of potassium carbonate in 2 mL of dry DMF. The mixture was heated in an oil bath maintained at 130° C. for 18 h. After cooling to room temperature, the mixture was poured into 150 mL of water and stirred for 0.5 h. The product was isolated by filtration and washed with fresh water. The title compound (0.9 g; 68% yield) was purified by flash chromatography on silica gel, eluting with a gradient of hexanes(75-15%)/Et3N(5%)/THF(20-80%). Conversion to the trioxalate was effected as in Example 137, Part E.
