Abstract: Quinolinic anhydride and NH2CSNHNH2 in aq. NH3 (1 hr. at 193°, or 30 min. at 42°) give 1,4-di(β-isoquinolinoyl)thiosemicarbazide, C15H7O4N5S (I), m. 267-8° (Ag salt, sinters 234°, decomp. 243°; Ac deriv., C17H9O5N5S, sinters 200°, m. 200-25°). In boiling Ac2O the product is 1,4-dinicotinoylthiosemicarbazide, C13H11O2N5S (tri A g salt; tri-A c deriv., C19H17O5N5S). Reaction did not occur in C6H6 or PhMe.
