150 g of formamide are stirred together with 90 mL of 30%ig sodium methylate solution for 8 hours under slight vacuum at 80° C. To the resulting solution of sodium diformylamide there are added 150 g of 4-chloromethylbenzophenone. After 15 hours the suspension originally present has changed to a clear solution which is added to 1l of 10%ig sodium carbonate solution. A solid material precipitates, which is filtered off in vacuo and dried.
