91% | 152 g of 1 mol of 2-chloroacetaldehyde diethyl acetal (i.e., a compound of formula III) was added to 500 ml of toluene.Obtaining an organic mixed solution of 2-chloroacetaldehyde diethyl acetal, temperature control 10 C,Then add 100 ml to the organic mixed solution of 2-chloroacetaldehyde diethyl acetal.Concentrated hydrochloric acid (1.2 moL) with a substance concentration of 12 mol/L,Stir for 20 minutes after the addition is complete.Dissolve to obtain an organic phase,To the organic phase, 260 g of 2 mol of ethyl 3-amino-3-iminopropionate (ie, the compound of formula II) was added in three portions, and the mixture was heated to 80 C for 3 h, filtered, and the filtrate was concentrated to give 140 g of 2-amino- 3-carboxypyrroleethyl ester (i.e., a compound of formula IV) in a yield of 91%. |
