Versuchsvorschrift

The nitroso compound of Procedure 92 was reduced with sodium dithionate in formic acid according to the method of Procedure 21. The resulting 6-formylamino compound, 1.3 g. (0.0041 mole), was suspended in 40 ml. of water containing 0.0043 mole of NaOH and the mixture was heated on the steam bath until dissolution occurred. The solution was treated with charcoal, filtered, cooled and acidified with HOAc to yield the desired product, 0.85 g., recrystallized from MeOH, yield 0.60 g., hemihydrate m.p. 314°-316° d.
