Versuchsvorschrift

To a stirred and cooled (ice-bath) solution of 27.5 parts of 2-bromoethanamine hydrobromide in 200 parts of water is added a solution of 28.9 parts of 4-methoxy-2-nitrobenzoyl chloride in 63 parts of benzene at 5°-10° C. While stirring vigorously, there is added dropwise a solution of 10.8 parts of sodium hydroxide in 250 parts of water at 5°-10° C. Upon completion, stirring is continued for 2 hours at this temperature. The supernatant phase is decanted and the oily residue is stirred in 2-propanol. The product is filtered off and dried, yielding 27.5 parts (68%) of N-(2-bromoethyl)-4-methoxy-2-nitrobenzamide; mp. 133.8° C.
