In a reactor under 200 psi of pressure was added (6.2 g, 22 mmol) of methyl (2R)-2-[(tert-butoxycarbonyl)amino]-3-(1H-indol-3-yl)propanoate and 120 ml of methanol saturated with NH3. The solution was stirred at about 85° C. for about 24 hours. After cooling, the solution was evaporated and the residue precipitated by the addition of diisopropyl ether. Filtration gave 5.4 g of the title product as a white powder. Melting point: 142-143° C.
