PROCESS FOR PRODUCING N-BENZYL-2,2-DIMETHOXY-ACETAMIDE DERIVATIVES

摘要

N-benzyl-2,2-dimethoxy-acetamides having the formula 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.
