• N-(5,6-Dihydro-4-benzo [h] quinazolinyl) amino acids (III and VII) were synthesized by condensation of 4-chloro-5,6-dihydrobenzo [h] quinazoline (II) with several amino acids and were cyclized to 4,5-dihydrobenz [h] imidazo [1,2-c] quinazoline derivatives, i.e., 11,13,15-triazasteroidal compounds (IV, V, VI, VIII, and IX) using phosphoryl chloride or acetic anhydride. An oxygen function could be introduced at C-1 of 4,5-dihydrobenz [h] imidazo [1,2-c] quinazoline, i.e., C-17 of the 11,13,15-triazasteroidal compounds.
