Procedure

A mixture of 6-(2,3-dichloro-4-butyrylphenoxy)hexanoic acid (9.5 g, 0.026 mole), dimethylamine hydrochloride (15 g, 0.184 mole), paraformaldehyde (2.8 g, 0.09 equiv.) and acetic acid (1 ml) were united and stirred and heated on a steam bath for two hours. The reaction mixture was treated with N,N-dimethylformamide (30 ml) and stirring and heating continued for another hour. The reaction mixture was poured into ice water and the solid that separated was removed by filtration, washed with water and dried. The yield was 9.2 g after recrystallization from butyl chloride the 6-[2,3-dichloro-4-(2-methylenebutyryl)phenoxy]hexanoic acid melted at 106°-107° C.
