Reaction Steps

0.3 mL of 1N sodium hydroxide and 1.0 mL of water were added to a solution of 0.040 g of Compound 3D in 1.8 mL of MeOH and 0.9 mL of 1,4-dioxane at 20-25° C., while stirring. The mixture was heated at 50° C. for 3.5 hours. After cooling to 20-25° C., the mixture was diluted with water and acidified to pH 1 with 3N hydrochloric acid. The precipitated solid was collected by filtration and washed with water to afford 0.028 g (73.5%) of the title compound, melting at 269-275° C.
