Procedure

1.59 g of the nitro compound obtained in Example 40, 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 obtain 5-(7-aminobenzoxazol-2-yl)tetrazole.
