Reaction Steps
A solution of 4.8 mL (0.062 mole) of potassium t-butoxide 1.OM in THF added dropwise to 10 g (0.048 mole) of (4-chlorophenyl)-1H-pyrrol-2-ylmethanone in 60 mL of THF. After stirring for 20 minutes, a solution of 5.6 mL (0.062 mole) of chloroethylmethyl ether in 40 mL of THF was added dropwise. The reaction mixture was refluxed for 72 h after which 5 mL of chloroethylmethyl ether was added and refluxing continued overnight. Another 5 mL of chloroethylmethyl ether was added with an additional 24 h of refluxing. The reaction was poured into water and extracted with Et2O. The organics were washed with water, brine and dried (MgSO4). The solvent was evaporated in vacuo to give 10.5 g (83%) of [(4-chlorophenyl)-1-ethylmethoxy-1H-pyrrol-2-yl]methanone.
