Procedure

To a solution of lithium aluminum hydride (1M solution, 70 ml) cooled to 0° C., was added a solution of N-(3-fluoro-4-pyridinyl)-N-(1H-indol-1-yl)glycine ethyl ester (11.4 g) in 125 ml tetrahydrofuran in thirty minutes. After stirring at 0° C. for one hour, a solution of ammonium chloride was added, followed by 300 ml ethyl ether. The mixture was filtered, and the filtrate evaporated to a solid 10 g; which was eluted on a silica gel column with ethyl acetate/dichloromethane (1:1) via HPLC. The desired fractions were combined, then evaporated to yield 6.1 g of N-(3-fluoropyridin-4-yl)-N-(1H-indol-1-yl)-2-aminoethanol, as a solid, m.p. 133°-5° C.
