Procedure
The compound (42) (1.68 g) was esterified in the conventional procedure with 1,8-diazabicyclo[5.4.0]-7-undecene (DBU, 0.78 ml) and isopropyl iodide (0.35 ml) in acetonitrile (15 ml). The residue was subjected to silicagel column chromatography to give the titled compound (43). Yield: 0.908 g (88%)
