YieldReaction ConditionsOperation in experiment
With sodium hydroxide In ethanol; water 1 Preparation of 4-Chloro-2-methylbenzoic Acid, 2,2-bis(2-fluoroethyl)hydrazide (Compound No. 1) Example 1 Preparation of 4-Chloro-2-methylbenzoic Acid, 2,2-bis(2-fluoroethyl)hydrazide (Compound No. 1) To 50 mL of ethanol was added 5 gm of 4-chloro-2-methylbenzhydrazide followed by 4 gm of sodium hydroxide pellets. After stirring for 15 min, 7.5 gm of 1-bromo-2-fluoroethane was added dropwise. After this addition was complete, the resulting mixture was stirred for 4 hours, then diluted with 100 mL of water, and, finally, extracted with ethyl acetate. Upon evaporation of the solvent, an oil remained which was purified by chromatography, to produce 1.7 g of 4-chloro-2-methylbenzoic acid, 2,2-bis(2-fluoroethyl)hydrazide as an off white solid, mp 85°-87° C. The compounds summarized in Table 1 were prepared using an analogous procedure. Each of the compounds is characterized by its NMR data.
