Imidazole compounds, process for preparation, medicaments based on these compounds and some intermediates

摘要

Imidazole derivs. of formula (I) and their salts are new. R1 = 1-6C alkyl. R2, R3 = independently H, F, Cl, Br, I or 1-3C alkyl. X = OH or -NR4R5. R4 = H or 1-7(1-4)C alkyl, opt. substd. by CN, NH2 or CO2H. R5 = 1-8 (1-5)C alkyl, opt. interrupted by phenyl and opt. substd. by not less than 1 OH, 1-3C alkoxy, (un)substd. phenyl, CO2H, CO2-(1-3C alkyl), -CONH2, CN, 2-5C alkynyl, NH2, NHR6, N(R6)2, N+(R6)3, NH-CO-(1-6C alkyl), a gp. of formula (i), a monocyclic 5-7 membered (un)saturated opt. substd. heterocycle with one N heteroatom, and opt. an extra N, O or S heteroatom, where the S atom can be oxidised to SO or SO2. Alternatively, R4 and R5 together form a 5-7 membered opt. substd. heterocycle which may contain, in addn. to the amide N atom, a further N, O or S heteroatom. The heterocycle is not morpholine. R6 = independently 1-4C alkyl, 2-6C alkoxyalkyl or phenyl-(1-3C alkyl). N-(2-morpholinoethyl)-1-methyl -2-imidazolsulphonic acid amide and N-(2-morpholinopropyl) -1-methyl-4-imidazolsulphonic acid amide are specifically claimed. Also claimed.are methods for preparing (I), e.g. by sulphonation of the corresponding mono-, di- or trisubstituted imidazole cpd.
