| abstract | 1277445 Phenanthridine derivatives ORGANON LABORATORIES Ltd 8 July 1969 [21 Aug 1968] 34299/69 Heading C2C Novel compounds I in which R 1 and R 2 are H, halo, OH, amino, acyloxy, 1-6 C alkyl or 1-6 C alkoxy ; R 3 is H, OH, halo, 1-6 C alkyl or 1-6 C alkoxy; X is O ; (CH 2 )n is a 1-6 C branched or unbranched alkylene radical; and R 4 and R 5 are 1-6 C alkyl, H or together with N form a saturated or unsaturated heterocyclic ring and the acid addition and quaternary ammonium salts thereof are prepared by reacting a compound II with Y-C( = X)-(CH 2 ) n -Z in which Z is halo, or -NR 4 R 6 and Y is halo, OH or the group -OCO(CH 2 ) n -Z or hydrocarbyloxy followed (1) where Z is halo by reaction with HNR 4 R 5 or (2) by modification of the group R 3 in a conventional manner, if desired. Intermediates isolated are (A) N-acetyl-2- phenyl-aniline, prepared from o-biphenylamine and acetyl chloride, (B) 6-methyl phenanthridine, prepared by cyclization of A with polyphosphoric acid; (C) 5,6-dihydro-6-methyl phenanthridine, prepared from B by reduction; (D) N-chloroacetyl-5,6-dihydro-6-methyl -phenanthridine, prepared from C; and 5,6-dihydro-6-ethyl-phenanthridine; 5,6-dihydro-6-hydroxymethyl-phenanthridine; N-chloroacetyl-6-hydroxymethyl-5,6- dihydro-phenanthridine; 2-bromo-6-methyl-5,6- dihydro-phenanthridine; 6 -methoxymethyl-phenanthridine; 6-methoxymethyl-5, 6-dihydro-phenanthridine and its N-chloroacetyl derivative; all prepared similarly to B-D 6-phenanthridinecarboxylic acid methyl ester, prepared from the acid; 5,6-dihydro-N-chloroacetyl-6-hydroxymethyl-phenanthridine and 5,6-dihydro-N-chloroacetyl- 6-chloromethyl-phenanthridine. Pharmaceutical compositions comprise a compound I and a suitable carrier, have antidepressive, anti-ulcer and antiserotinic activity and can be administered orally and parenterally. |
