Pyridine → Cyclohexyl 4-chloro-3-nitrobenzoate

Participants

Reaction Steps

Twelve grams (0.055 mole) for crude 3-nitro-4-chlorobenzoyl chloride were dissolved in 200 ml. of benzene. Eight milliliters of pyridine were added to the reaction mixture. Six milliliters of cyclohexanol were dissolved in 50 ml. of benzene and the solution was added dropwise to the acid chloride-pyridine mixture. The reaction mixture was refluxed for 4 hours and filtered. The benzene filtrate was washed successively with dilute acid, dilute base and water. The washed benzene solution was dried and evaporated in vacuo to yield 12.5 g (88 percent) of cyclohexyl 3-nitro-4-chlorobenzoate, mp 57°-58° C.
