Reaction Steps

To platinum oxide (1.0 g) was added 100C in ethanol (70 mL) and hydrogen chloride (0.6 ml) under nitrogen. The reaction was placed under hydrogen (40 psi). After 3 h the reaction was half done, the catalyst was filtered and the solvent was removed. Fresh platinum oxide was added (1.0 g) and the reaction was stirred under hydrogen (40 psi) for 2 h. The catalyst was filtered over celite and washed with ethanol. The filtrate was neutralized with diethylamine. The solvent was evaporated and the crude residue was redissolved in dichloromethane. The organic layer was washed with water, brine and dried over sodium sulfate. The solvent was removed and the crude product was dried under vacuum to give a white solid 100D (2.0 g).
