Reaction Conditions:
with sulfuric acid for 6 h;Reflux;Fischer–Speier Esterification;
Steps:
General procedure for obtaining alkyl 2-chloroacetates via Fisher esterification (5a-5h)
General procedure: A mixture of 2-chloroacetic acid (20 mmol), the respective alcohol (4a-4h) (60 mL) and concentrated sulfuric acid (1 mL) was refluxed for 6 h. Afterwards,the excess solvent was rotary-evaporated, and the residue poured into cold water. The residue was transferred to a separation funnel containing 250 mL of water, and 100 mLof ethyl ether were then added. The organic phase was separated, washed repeatedly with 10% sodium bicarbonate until neutral pH and then dried with anhydrous NaSO4. Ethyl ether was rotary-evaporated, obtaining the respective esters (5a-5h).
