O:33.89 N:9.69It can be obtained by reacting a mineral acid salt of acetate amide represented by the formula (X: halogen, HSO 4 , NO 3 ) in the presence of a solvent. The reaction temperature is preferably 50°C to 150°C. The reaction time varies depending on the combination of raw materials used, reaction temperature, reaction solvent, etc., but is approximately 1 to 20 hours. Further, the concentration of the compounds of general formulas (2) and (3) in the reaction solution is preferably 5 to 20 wt%. Examples of solvents include solvents inert to mineral acid salts of alkali formyl acetate and acetate amide.
DMF, SMSO, THF, diethyl ether, etc. are suitable. The raw material alkali forsylacetate can be obtained by reacting carbon monoxide, an alkali alcoholate, and an acetate. This invention will be explained below with reference to Examples. Example: 2.48 g (20 mmol) of sodium formyl methyl acetate in a 100 ml three-necked flask with a Dimroth condenser.
and 50 ml of dimethylformamide were added thereto, and 1.91 g (20 mmol) of acetic acid amide hydrochloride was added while stirring at room temperature. After raising the temperature to 100℃ and stirring for 4 hours,
The solvent was distilled off under reduced pressure and the residue was separated and purified by column chromatography to obtain 1.1 g (7.7 mmol) of methyl β-acetylaminoacrylate. This compound was identified based on the physical property data shown below.・IR spectrum (kBr, cm -1 ) 1713cm -1 1690cm -1 1620cm -1・NMR spectrum (cDCl 3 , ppm) H a 3.73 (singlet) H b cis 5.08-5.16 (double) trans 5.40-5.55 (double) H c cis 7.61-7.45 (triplet) trans 7.83-8.13 (triplet) line) H d 8.92 to 9.34 (wide peak) H e 2.14 (single line) Elemental analysis value Calculated value C: 50.35 H: 6.29 O: 33.57 N: 9.79 Actual value C: 50.01 H: 6.41 O: 33.89 N:9.69
