6-(6-Morpholin-4-yl-4-oxo-4H-pyran-2-yl)-thianthrene-2-carboxylic acid methyl ester (1.1 g, 2.43 mmol) and NaOH Pellets (97 mg, 2.43 mmol) were dissolved in methanol (40 ml). The brown suspension was heated to 80° C. under N2 for 24 hours. The solvent was removed in vacuo and the residue was triturated with diethyl ether. The product was collected by filtration as a fine dark brown powder (1.11 g, 99%). m/z (LC-MS, ESP), RT=3.90 min, (M++1)=438
