反応手順
To 1.0 g of E-6-(1,3-dihydro-4-carbamoyloxy-6-methoxy-7-methyl-3-oxo-5-isobenzofuranyl)-4-methyl-4-hexenoic acid dissolved in 20 ml of dry THF is added 0.59 g of dicyclohexylcarbodiimide and 0.037 g of N-(2-hydroxyethyl)morpholine. The mixture is left at room temperature for 6 hours, then evaporated to dryness. The residue is chromatographed on silica gel, eluting with 50:1 dichloromethane:methanol, to give morpholinoethyl E-6-(1,3-dihydro-4-carbamoyloxy-6-methoxy-7-methyl-3-oxo-5-isobenzofuranyl)-4-methyl-4-hexenoate.
