The present invention relates to methods for preparing and manufacturing a crystalline form or polymorph of a compound of formula I:
in the form of pharmaceutically acceptable salts and polymorphs thereof. The present invention is directed to methods for preparing and manufacturing crystalline polymorphs or forms of specific anilino-pyrimidine benzenesulfonamide compounds. Methods for converting one crystalline form or polymorph of compounds of formula I as their pharmaceutically acceptable salt polymorph to other different crystalline polymorphs of compounds of formula I as their corresponding pharmaceutically acceptable salt are also disclosed.
Characterization of directly acting mutagens produced from N-nitroso-N-(formylmethyl)alkylamines: Their possible involvement in the carcinogenesis of N-nitrosamines having a 2-hydroxyethyl group.
Directly acting mutagens formed from N-nitroso-N- (formylmethyl) alkylamines (3) were isolated and identified as N-nitroso-N-alkyl-1-hydroxyimino-2-oxoethylamines (4). Their structures were elucidated on the basis of nuclear magnetic resonance spectra and confirmed by derivatization to the crystalline 2, 4-dinitrophenylhydrazones (5). Compounds 4 (alkyl =ethyl and butyl) were strongly mutagenic to Salmonella typhimurium TA 1535 and Escherichia coli WP2 hcr- without metabolic activation, while 4 with a tert-butyl group was not mutagenic. The formation of 4 is considered to proceed by the nitrosation of 3, indicating a possible involvement of the formylmethyl metabolite in carcinogenesis by N-nitrosamines with a 2-hydroxyethyl group.
