Methyl iodide → HCID 22117266, compound

Participants

Reaction Steps

n-Butyllithium (52.8 ml of a 2.5M solution in hexanes) was added dropwise to a stirred solution of the product of step (i) (27.6 g) in tetrahydrofuran (100 ml)at -20° C. After 2 hours methyl iodide (85.3 g) was added and the mixture was stirred for 2 hours at this temperature then 0.5 hours at room temperature. The reaction mixture was partitioned between brine and ethyl acetate. The aqueous solution was extracted with ethyl acetate. The organic solution was dried (MgSO4) and evaporated under reduced pressure. Purification was by chromatography eluting with 5% ethyl acetate inisohexane. Used without further purification.
