Abstract

Benzo-furanyl-carbamate intermediates i.e. complexes of 3 moles of 2,3-di:hydro-2,2-dimethyl 7-dibenzo-furanol and its ion and 1 mole of an alkali metal-ion are prepd. from (a) 2,3-dihydro-2,2-dimethyl 7-benzo-furanol and an alkali carbonate 1:0.25-0.3 in aq. and/or solvent medium or (b) 2,3-dihydro-2,2-dimethyl 7-benzo-furanol and an alkali-hydroxide 1:0.2-0.3 in aq. and/or solvent medium, or (c) 2,3-dihydro-2,2 dimethyl 7-benzo-furanol-alkali salt:alkali hydrogen carbonate 1:0.75. - An alternative prepn. of benzo-furanyl-carbamate derivs. (II) comprise reactions between the preceding intermediates and known reagents suitable for the introduction of carbonoyl gps. of general formula -CO-N(CH3)-R1, R1 is a H atom or a gp. of general formula (III). R2 is a substd. alkyl gp., R3 an alkyl gp. Both R2 and R3 can be selected to form a morpholinyl or piperidinyl gp. with the use of the adjacent N atom.
