실험 절차

The title compound is prepared by the procedure of Example 257 using 0.342 g of product from Example 192 in 10 ml of pH 7 0.1M sodium dihydrogen phosphate buffer, 0.407 g of product from Example 299 in 7 ml of dioxane to give after chromatography (Reverse Phase plates: 25% acetonitrile/water) an oil. The oil is mixed with 0.10 g of 10% palladium on carbon, 10 ml of pH 7 0.1M sodium dihydrogen phosphate buffer and 5 ml of dioxane. The solution is reduced in a Parr apparatus at 47 psi of hydrogen for 3 hours, The reaction mixture is filtered, the filtrate is concentrated in vacuo to a small volume and purified by chromatography (Reverse phase plates: 25% acetonitrile/water) to give 0.090 g of the desired product.
