실험 절차
Using the procedure of example 184, 2,3-dihydro-7-hydroxy-8-propyl-4H-1-benzopyran-4-one was converted into the title compound by alkylation with 2-(4-methoxy-4-oxobutoxy)-6-[6-(methylsulfonyl)oxyhexyl]benzenepropanoic acid methyl ester from the preceding example, followed by saponification, in 40% overall yield. The product was a colorless solid, mp 116°-117.5° C., recrystallized from acetonitrile.
