Procedure

A solution of 9b-amino-4b-hydroxy-7-isopropyl-4b,9b-dihydro-5-oxa-indeno[2,1-a]inden-10-one (0.20 g, 0.67 mmol) in anhydrous methylene chloride (10 ml) was added triethylamine (0.20 g, 2.01 mmol) and heptanoyl chloride (0.25 g, 1.69 mmol) and then stirred for 3 hrs. The reaction mixture was concented and extracted with ethylacetate. The concentrated organic layer was purified using silica gel column chromatography (ethylacetate:hexane=1:6 to 1:4) to afford the title compound as a syrup (0.21 g, 60%).
