METHOD OF OBTAINING NITROMETHANE DERIVATIVES

摘要

Compounds of the formula Q-SO2-CH2-NO2 in which Q is an aromatic moiety of 6, 10 or 14 atoms, optionally bearing 1, 2 or 3 substituents which are independently selected from: hydrogen, halogeno, cyano, nitro, hydroxy, carboxy, amino, alkylamino or dialkylamino of up to 6 carbon atoms, (1-6C)alkanoylamino, (1-6C)alkanoyl, (1-6C)alkyl, (2-6C)alkenyl, (3-6C)alkenyloxy, fluoro(1-4C)alkyl, (1-6C)alkoxy, fluoro(1-4C)alkoxy, hydroxy(1-6C)alkyl, (1-4C)alkoxy(1-4C)alkyl, carbamoyl, alkyl or dialkylcarbamoyl of up to 7 carbon atoms, sulphamoyl, alkyl or dialkylsulphamoyl of up to 6 carbon atoms, (1-6C)alkoxycarbonyl, (1-4C)alkylenedioxy, (1-6C)alkanesulphonamido, (1-6C)alkyl.S(O)n- [in which n is zero, 1 or 2], phenyl, phenoxy, benzyloxy, benzyloxycarbonyl, benzamido and benzenesulphonamide, the benzene moiety of the last six groups optionally bearing a halogeno, (1-4C)alkyl or (1-4C)alkoxy substituent; or Q bears 4 or 5 substituents independently selected from halogeno, cyano, (1-6C)alkyl or (1-6C)alkoxy; but excluding the compounds in which Q is 2-carboxy-phenyl; are used in pharmaceutical compositions. These compounds may be prepared starting from: -an alkali metal sulfinate and nitromethane -a sulfone and an alkylnitrate -a thioether.
