2-(Dimethylamino)ethanol → HCID 21255081, compound

Participants

Reaction Steps

A solution of 2-dimethylaminoethanol (1 mL) in THF (20 mL) was treated with potassium tert-butoxide (1.2 g). After 5 min, chloropyrazine (2 g) was added and the reaction stirred 2 h. The solvent was evaporated, the residue suspended in cold water, the mixture acidified, and the mixture extracted with ether. The aqueous fraction was made basic and extracted with EtOAc. The extracts were dried, the solvent evaporated, and the residue purified by radial chromatography eluting with 10%-EtOH-1%—NH4OH—CHCl3 to give 2-(2-dimethylaminoethoxy)pyrazine (1.3 g). The HCl salt crystallized from 2-propanol as a white solid, m.p. 151-153° C. (Compound 26).
