DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Pyridinesulfonylcarbamates [I; R-R2 = alkyl], useful as intermediates for herbicides, are prepd. by reaction of pyridinesulfonamides (II) with XCO2R (X = halo). ClCO2Et was added to a mixt. of II (R1 = R2 = Me) and K2CO3 in MeCN at room temp. and the mixt.Several substances are used for example 144098-17-9 which is its cas registry number. was refluxed to give 90.8% I (R = Et, R1 = R2 = Me), which was refluxed with 2-amino-4,6-dimethoxyprimidine in MePh to give 94.9% herbicidal (no data) urea deriv.
