One-pot reactions between carboxylic hydrazides and 2-isothiocyanatobenzonitrile afforded pharmacologically relevant 1,2,4-triazolo[1,5-c]quinazoline-5(6H)-thiones in good yields. These compounds were transformed into the corresponding amino-substituted derivatives in good yields in one of two steps. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
