실험 절차

The product from Step 1 (8.7 g, 52.0 mmol) in ethanol (150 ml) was hydrogenated for 18 hours in the presence of 10% palladium on carbon. After filtration of the catalyst through Kieselguhr, the filtrate was concentrated in vacuo to afford the title compound (6.7 g, 94%); MS (ES+) m/e 138 [M+H]+.
