| abstract | 1333649 Thiaxanthene-derived aminoketones STERLING DRUG Inc 4 Oct 1971 [5 Oct 1970 (2)] 46157/71 Heading C2C The invention comprises compounds of formula and their acid addition salts, wherein R is H or Me; Y is C 2-4 alkylene; R 1 , R 2 are each C 1-6 alkyl (possibly OH-substituted), or NR 1 R 2 is a saturated N-heteromonocyclic radical containing 5-7 ring atoms; the 2 N atoms being separated by at least 2 C atoms and the compounds may be substituted in the 5, 6, 7 or 8 positions by 1 or 2 of halogen, C 1-6 alkyl and C 1-6 alkoxy. These compounds, which are prepared by reacting 1-chlorothiaxanthen-9-one with R 1 R 2 NYNHR, may be converted to the 4-hydroxymethyl derivatives by reaction with (a) excess CH 2 O under acidic conditions, or (b) HCONME 2 +POCl 3 , followed by reduction of the 4-formyl derivatives so formed; the reduction may be preceded by reaction with pyridine hydrochloride to replace R = Me by H. |
