Reaction Steps

The title compound is prepared by the reaction of the intermediate prepared in Example 11 with ethanolamine and sodium hydroxide. The aqueous layer is removed, and the remaining layer is extracted with cyclohexane. Solvent is evaporated at reduced pressure, and the crude product is purified by flash chromatography on silica gel with 1:2 (v/v) hexane/ethyl acetate to afford 4.1 g of the title compound as a white solid, melting at 110-120° C.
