Abstract

Abstract The ureas obtained from 1-amino-3 (or 4)-methyl-2-naphthalenecarbonitrile and 2- chloroethyl isocyanate, or ethyl isocyanatoacetate undergo a double cyclization upon thermal decomposition, or treatment with base to yield compounds with the benz [h] imidazo [1, 2-c] quinazoline ring system.
