Reaction Steps

(6-Hydroxy-1H-indol-2-ylmethyl)-carbamic acid benzyl ester was dissolved in 10 ml acetone, Cs2CO3 and diethyl chloromalonate were added. The reaction is stirred overnight. HPLC and TLC indicated the reaction is done. The mixture was diluted with ethyl acetate and filtered through silica gel plug. The filtrate is concentrated and redissolved in ethanol, hydrogenated for 3 hours at 40 psi of hydrogen. The mixture is filtered, washed with ethyl acetate. The filtrate is concentrated to give 2-(2-Aminomethyl-1H-indol-6-yloxy)-malonic acid diethyl ester.
