A solution of MTT in an organic solvent and water (20%) was heated for 4-8 hrs at reflux. When the solvents were either acetonitrile (ACN), isopropyl alcohol (IPA) or t-butanol (t-BuOH), 1 volume of water was added, and the reaction was stirred until the amount of MTT was less than 2%. The mixture was evaporated to dryness. Ethyl acetate (EtOAc, 1 volume) was added to the residue and then evaporated again (twice). The resulting solid was dissolved in EtOAc (12 vol) and heated to reflux. The solution was cooled (2 C.) and stirred for 2 hrs. The product was filtered, washed (EtOAc, 1 vol), and dried on vacuum (45 C.).

At the end of this time, 75 ml of water were added to the mixture, which was then cooled. Precipitated trityl alcohol was removed by filtration, and the filtrate was concentrated by evaporation under reduced pressure. Toluene was added to the residue, and the mixture was again concentrated by evaporation under reduced pressure, to remove the remaining water and acetic acid. The residue was crystallized in ethyl acetate, to give 16.6 g of the title compound as crystals, melting at 177-180 C. (with decomposition). The Nuclear Magnetic Resonance Spectrum of this compound was identical with that of the compound obtained as described in Example 61(b).
