実験手順

20 g (103 millimoles) of β-(p-aminobenzoyl)-propionic acid and 12.9 g (114 millimoles) of chloroacetyl chloride, together with 200 ml of absolute toluene, are kept for 4 hours at 80° C. The product is filtered off at 10° C., washed with water and dried under reduced pressure at 50° C. 25.1 g (90% of theory) of β-(p-chloroacetylaminobenzoyl)-propionic acid are isolated as light brown crystals which, after recrystallization from acetone, melt at 184°-185° C.
