Procedure

A solution of 2-chloroethylamine hydrochloride (6.25 g) in dry dimethylformamide was added dropwise to a stirred, cooled solution of potassium tert-butoxide (8.96 g) and 5-(dimethylamino)methyl-2-furanmethanol (12.4 g) in the same solvent. After 2 hr solvent was removed, the residue basified and extracted with ethyl acetate. The residue after removal of solvent was treated in ethanol with ethanolic oxalic acid. The crystalline salt was recrystallised from ethanol to give 2-[[5-(dimethylamino)methyl-2-furanyl]methoxy]ethanamine, bis oxalate, m.p. 130°-133° (3.05 g).
