Participants

Reaction Steps

To a solution of 1.7 g. of n-isopropylcyclohexylamine in 15 ml. of tetrahydrofuran, at -78°, is added 5.5 ml. of a 2.4 N n-butyl lithium n-hexane solution. Then 3 g. of ethyl arachidonate in 150 ml. of tetrahydrofuran is added dropwise, over a 2-hour period, at -78°. Then 1.5 ml. of methyl iodide is added and the mixture is allowed to warm to room temperature. The solution is concentrated by evaporating tetrahydrofuran, then extracted with ether to yield ethyl 2-methylarachidonate.
