2-Ethyl-2-oxazoline oxazolines towards ring-opening by chloride ions during protonation of the imine nitrogen. The direct reaction of propanoyl chloride with 2-chloroethylamine hydrochloride in the presence of triethylamine avoids the formation of water. Propanal reacts with 2-aminoethanol in "t"-butanol to 2-ethyl-2-oxazoline in the presence of the iodinating reagent 1,3-diiodo-5,5-dimethylhydantoin (DIH) and potassium carbonate. 2-Ethyl-2-oxazoline is a readily water-soluble, colorless liquid which is also soluble in a variety of organic solvents and possesses an amine-like smell. Aqueous solutions react alkaline. The compound is stable in alkaline but hydrolyses under acid action. In anhydrous form, 2-ethyl-2-oxazoline is mostly used as a monomer. The cationic
N-Ethyl-3-piperidyl benzilate Schedule I controlled drugs. Radiolabelled versions of this drug have been used in scientific research to map the distribution of muscarinic acetylcholine receptors in the brain, however this drug has slightly lower binding affinity than the N-methyl analogue and so is less potent and not so widely used for this application. N-Ethyl-3-piperidyl benzilate "N"-Ethyl-3-piperidyl benzilate (JB-318) is an anticholinergic drug related to the chemical warfare agent 3-Quinuclidinyl benzilate. "N"-Ethyl-3-piperidyl benzilate is less potent and shorter acting than 3-quinuclidyl benzilate, but like 3-QNB its effects on the central nervous system predominate over peripheral effects. It produces deliriant and hallucinogenic effects similar
