Procedure

The title compound was prepared by the same method as described for compound of Example 97, but using the compound prepared in Example 124 instead of compound of Example 94. The reaction mixture was diluted with water and 3N aqueous sodium hydroxide solution, under vigorous stirring. The precipitated solid was filtered by suction, washed with water, desiccated and purified by flash chromatography on silica gel eluting with ethyl acetate - methanol (8.5:1.5). Evaporation in vacuo of the collected fractions yielded the title compound which melted at 146°-150° C. after crystallization from acetonitrile.
