Reaction Steps

The compound obtained in Example 339 (0.77 g, 2.0 mmol) was dissolved in a mixture of dimethylformamide (6 ml), methanol (11 ml), and 5% HCl-methanol solution (2 ml). To the resultant solution, 10% palladium-on-carbon (0.30 g) was added, followed by stirring at ambient temperature for 2 hours in the stream of hydrogen. The palladium-on-carbon was filtered off, and the solvent was distilled off under reduced pressure. 0.438 g of the title compound was obtained as pale yellow crystals (76.5%).
