Triethylamine → HCID 22020971, compound

Participants

Reaction Steps

A solution of intermediate (5) (0.018 mol) and triethyl amine (0.036 mol) in DCM (80 ml) was stirred and cooled with an ice-water bath. Methanesulfonyl chloride (0.027 mol) was added dropwise and the resulting reaction mixture was stirred for one hour while cooling on an ice-bath. The crude reaction mixture was washed with water and brine, then extracted. The separated organic layer was dried, filtered and the solvent was evaporated, yielding 4.2 g of (±)-1,3-dioxolo[4,5-b]pyridine-2-methanol methanesulfonate (ester) (intermediate 6).
