Thiazole derivatives of the formula:
wherein each of R' and R independently represent hydrogen, C1-4 alkyl, benzyl or benzoyl, or, taken together with the adjacent nitrogen atom, form a saturated heterocyclic ring containing from 5 to 7 ring atoms,
R3 is hydrogen or C1-4 alkyl,
Z is 0, S, or CH2,
n is 2 or 3 when Z is 0 or S and n is 1, 2 or 3 when Z is CH2,
R5 is hydrogen or C1-4 alkyl,
m is 1, 2 or 3,
wherein A is N-CN, N-NO2, CH-NO2, S, 0, NH, N-SO2- aryl, N-SO2-C1-4 alkyl, N-CO-NH2, N-CO-C1-4 alkyl, N-CO2-C1-4 alkyl; CH-SO2-aryl or CH-SO2-C1-4 alkyl, wherein aryl is phenyl, halophenyl, C1-4 alkylphenyl or C1-4 alkoxyphenyl, and
B is NRR6, wherein R and R6 are independently hydrogen, C1-5 alkyl, C3-6 cycloalkylmethyl, hydroxy C2-5 alkyl, C3.6 cycloalkyl, alkoxyalkyl or dialkyl-aminoalkyl wherein the total number of carbons is less than 8 and there is at least a two-carbon chain between the hetero atoms, or YR4, wherein Y is oxygen or sulfur and R4 is C1-5 alkyl, -CH2 C2-4 alkenyl or benzyl, or a pharmaceutically acceptable salt of a compound in which B is NRR6, have been found to possess activity as H2 antagonists and are therefore of value as antiulcer agents.
