The title compound (II) was prepared by acid-catalysed hydrolysis of N,N-disubstituted β-methoxy-α-methylacryloylureas V-VIII. This reaction is accompanied by the parallel cleavage of the amide bond in the compounds V-VII leading to N,N-disubstituted ureas and α-formylpropionic acid.
目标化合物(II)是通过对N,N-二取代β-甲氧基-α-甲基丙烯酰基脲(V-VIII)进行酸催化水解制备而成。此反应伴随着化合物(V-VII)中酰胺键的并行裂解,形成N,N-二取代脲和α-甲酰基丙酸。
