Schönenberger, Helmut ; Kranzfelder, Gerhard ; Schmitt-Wallenborn, Helga


Six title compds. I (R = C1-6 alkyl, R1 = H, Me), useful in treating mammary tumors, were prepd. from 3-MeOC6H4CHO and alkylmagnesium halides. Thus, Grignard reaction of MeI with 3-MeOC6H4CHO gave 85.4% 3-MeOC6H4CH(OH)Me which was treated with HCl to give 73.3% 3-MeOC6H4CHClMe. Grignard reaction of this with EtBr gave 17.9% (3-MeOC6H4CHMe)2, ether cleavage of which with MeMgI or pyridine-HCl gave ...
