The title compds. (I) [R = H, alkyl(C1-C4), trifluoromethyl, Ar, - CH2-halogen, -CH2-(SO)n-CH3(n=0,1,2), -CH2CN, -CH2-N(R1,R2) (R1,R2=H, methyl), -CH2-O-CO-R3(R3=alkyl (C1-C4), etc..; R'alkyl(C1-C4), BCN(B=linear or branched lower alkyl), B-O-CO-R, BOR, CH2N(R1,R2), etc..; X = H, methyl, Cl, Ar, phenyl etc.; T = linear or branched alkyl(C1-C3); Z = O, S, SO, SO2, NH or a single bond were prepared by the reaction of compds. (II) and (III) [Z" = leaving group, in the case that R is not hydrogen, R' is hydrogen . The compds. (I) effectively control stomach acid secretions and protect alls.
