Versuchsvorschrift

Under an argon atmosphere, to a solution of 300 mg of 2-{4-[N-(5,6-diphenylpyrazin-2-yl)-N-isopropylamino]butyloxy}acetic acid obtained in Example 42 in 5 ml of anhydrous tetrahydrofuran, 128 mg of 1,1′-carbonyl diimidazole was added and, after stirring at room temperature for 30 minutes, the mixture was heated at reflux for 30 minutes. After air-cooling to room temperature, 69 mg of methanesulfonamide was added. After stirring for 10 minutes, 0.11 ml of 1,8-diazabicyclo[5.4.0.]-7-undecene was added dropwise. After stirring at room temperature overnight, the reaction solution was diluted with water and then extracted with diethyl ether. The extract was dried over anhydrous magnesium sulfate and the solvent was evaporated under reduced pressure, and then the residue was purified by silica gel column chromatography to obtain 272 mg of the desired compound.
