4-(4-Chlorophenyl)butanicacid

4-(p-chlorophenyl)butanoic acid (34a) A mixture of 4-(4-chlorophenyl)4-oxobutanoic acid (1 eq.), KOH (3 eq.) and hydrazine hydrate (2.2 eq.) in ethylene glycol was refluxed azeotropically at 120-130° C. for 5 hours, the temperature was increased gradually to 180° C. Heating under reflux was then continued at 190° C. for 3 hours. The reaction mixture was cooled to 25° C., diluted with water and poured into a solution 2.5N HCl to give white crystals of 4-(4-chlorophenyl)butanoic acid (89percent).4-(4-Chlorophenyl)butanoic acid: 4-(4-Chlorophenyl)-4-oxobutanoic acid (1.06 g, 5 mmol) and KOH (85percent by wt, 0.79 g, 12 mmol) were placed in a round-bottomed flask fitted with a Dean-Stark apparatus and a reflux condenser and suspended in diethylene glycol (10 mL) at RT. Then, hydrazine monohydrate (50percent by wt., 1.20 g, 12 mmol) was added slowly to the reaction at RT after which it was heated to 120- 130 °C for 2 h. The reaction became homogenous after heating for approximately 45 min. After 2 h, the temperature was increased to 180-200 °C and the reaction stirred for an additional 3 h to remove residual hydrazine and water via the Dean-Stark trap. The reaction was then cooled to RT, diluted with HA heterogeneous mixture of 3-(4-chlorobenzoyl)-propionic acid (20 g, 188.1 mmol), potassium hydroxide (11.7 g, 208.7 mmol), hydrazine monohydrate (10 mL, 205.1 mmol), and diethylene glycol (84 mL) were heated in a flask equipped with a Dean-Stark trap and condenser. The mixture became homogeneous on heating. The mixture maintained at 120-1304-(p-chlorophenyl)butanoic acid (35a).
