Reaction Steps

This product was synthesized as described in general procedure 2 except 4-(6-(3,4-dichlorophenyl)-5,6-dihydrobenzo[h]quinazolin-2-ylamino)phenethyl methanesulfonate was used instead of 4-(6-(3-bromophenyl)-5,6-dihydrobenzo[h]quinazolin-2-ylamino)phenethyl methanesulfonate and morpholine was used instead of piperidine to afford 6-(3,4-dichlorophenyl)-N-(4-(2-morpholinoethyl)phenyl)-5,6-dihydrobenzo[h]quinazolin-2-amine in 55% yield. M.p.=180-181° C. 1H NMR 400 MHz (CDCl3) δ 8.45-8.4 (m, 1H), 8.17 (s, 1H), 7.62 (d, J=8.4 Hz, 2H), 7.58-6.85 (m, 6H), 4.18-4.0 (m, 1H), 3.84-3.68 (m, 4H), 3.35-3.18 (m, 1H), 3.18-3.0 (m, 1H), 2.92-2.73 (m, 2H), 2.7-2.45 (m, 6H).
