Yield:-
Reaction Conditions:
with sodium hydroxide in ethanol;dichloromethane;
Steps:
1 Example 1
Using an analogous procedure to that described by Lombardi et al., Chemistry & Industry , 1990, 708, diazomethane was generated from a mixture of N -methyl-N -nitroso-4-toluenesulphonamide (31 g), ethanol (200 ml) and a saturated aqueous sodium hydroxide solution (35 ml) and bubbled though a solution of 2-amino-4,6-dimethoxybenzoic acid (15.9 g) in methylene chloride (280 ml) which had been cooled to 0°C. The resultant reaction mixture was evaporated and the residue was purified by column chromatography on silica using methylene chloride as eluent. There was thus obtained methyl 2-amino-4,6-dimethoxybenzoate (16.2 g); NMR Spectrum : (DMSOd6) 3.65 (s, 3H), 3.7 (s, 6H), 5.75 (s, 1H), 5.9 (s, 1H), 6.2 (br s, 2H).
