Method B): 5-Ethoxycarbonylphthalid (52 g, 0.25 mole) is suspended in 2-propanol (1000 mL). Ti(iPro)4 (38 g, 0.14 mole) is added and the mixture is refluxed for 3 hours. The reaction mixture is cooled to 0° C. and the crystals are filtered off and washed with cold 2-propanol (70 mL). Yield: 47 g, 85%. DSC onset 144° C.
