HCID 221448232-(5-Fluorobenzofur-7-yl)-1-aminoethane oxalate

Procedure

Beginning with 2-(5-fluorobenzofur-7-yl)propionamide (EXAMPLE 39), 2-(5-fluorobenzofur-7-yl)-1-aminoethane was prepared by borane reduction essentially as described in EXAMPLE 39. This amine was treated with oxalic acid to provide the title compound.
