N-benzyl-2,2-dimethoxy-acetamides having the formula ##STR1## and processes for preparing the same. These acetamides are useful for the production of 2H-3-isoquinolones by acid cyclization and said 2H-3-isoquinolones are in turn useful as starting materials inter alia in the synthesis of 1,4-dihydro-1,4-etheno-isoquinolin-3(2H)ones, which are valuable chemotherapeutic agents as disclosed in U.S. Pat. No. 3,781,436.
N-苄基-2,2-二甲氧基乙酰胺具有以下结构式,并且用于制备这些化合物的方法。这些乙酰胺对通过酸环化制备2H-3-异喹啉酮很有用,而这些2H-3-异喹啉酮则可作为合成1,4-二氢-1,4-乙烯-异喹啉-3(2H)酮等有价值的化疗药物的起始原料,这些信息在美国专利号3,781,436中有披露。
