Procedure

The synthesis method of Example 7-(2) was applied. The compound (3.94 g) obtained in (3) above, a 5M sodium methoxide-methanol solution (17 ml), methanol (20 ml) and aminoguanidine hydrochloride (9.39 g) were used as reagents. The mixture was stirred with refluxing for 18 hours and methanol was distilled away under reduced pressure. Water was added to the residue and the aqueous layer was adjusted to pH 3-4 with 3N hydrochloric acid to give 3.40 g of a pale-yellow solid that precipitated (yield 82%).
