실험 절차
1.59 g of the nitro compound obtained in Example 36, Step 3, above, is suspended in 46 ml of methanol to which 1 ml of concentrated hydrochloric acid, and 0.17 g of 5% palladium on carbon are added. The mixture is stirred under hydrogen at atmospheric pressure for 18 hours, filtered, and the filtrate concentrated in vacuo to 1.10 g 5-(8-amino-4-oxo-4H-1-benzopyran-2-yl)tetrazole.
