Procedure
Compound (28b) was dissolved in DMF, and chloromethyl pivalate was added to the solution, followed by stirring. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The extract was concentrated, and hexane was added to the residue. The mixture was subjected to decantation twice and to further decantation (twice) with petroleum benzine. The residue was dried through a vacuum pump to give the subject Compound (28c).
