Abstract
Procedure for the preparation of 2-carbalkoxyamino-benzimidazole derivatives of formula (I) **(See formula)** wherein R1 signifies C1 -C4 alcohol, R2 and R3, in each case independently of each other, signify hydrogen, C1 -C4 -alkoxy, halogen, trifluoromethyl, C1 -C4 -alkoxy or CN and X signify the grouping -O-SO2- or -SO2-O-, characterized in that a 2,1,4-benzothiadiazine derivative of formula (2) is reacted **(See formula)** where R1 through R3 and X have the same meanings as in formula (1) and R4 represents hydrogen, an acetyl or benzoyl radical and n is 0 or 1, with an acid or triphenylphosphine or, when R4 represents the acetyl or benzoyl radical, with a base, at a temperature between 40 and 120ºC and in a solvent.
