Steps:

40 (Synthesis of 4-(4-fluorophenoxy)butyric acid)

The resulting crude 4-(4-fluorophenoxy)butyric acid (precipitate) was dissolved in a small amount of hot methanol, and gradually cooled to recrystallize. Filtrated recrystallization materials were dried by vacuum pump to provide objective compound, 4-(4-fluorophenoxy)butyric acid. In this series of processes, the resulting 4-(4-fluorophenoxy)butyric acid was 52.7% in yield based on the raw material 4-bromoethylbutyrate. In order to verify that the resulting compound was the objective 4-(4-fluorophenoxy)butyric acid, NMR analysis was carried out by the following measuring apparatus under measuring condition to identify thestructure.
