Abstract

Nov., 1950 SULFUR ANALOGS OF@-CARBOLINES 4999 the same manner as was VI above, light-yellow prisms from methanol, mp 283-284", yield 55%. Anal. Calcd. for ClsHIONt: C, 82.56; H, 4.59; N, 12.83. isoquinolinemeltsat 249-250. Found: C, 82.21, 82.14; H, 5.98, 5.89; N, 12.57. In this case the ring closure yielded pure (V) directly so that no dehydrogenation was necessary. The isomeric 11H-pyrido [3, 4-a] carbazole (IV) melts at ...
