Procedure
To a mixture of the 2-t-butoxycarbonylamino-3-(1H-indol-3-yl)-N-(2-methoxybenzyl)propanamide prepared supra (25.1 g, 59.2 mmoles) and anisole (12 ml, 110.4 mmoles) at 0° C. was added dropwise an aqueous solution of trifluoroacetic acid (118 ml, 1.53 moles) in 50 ml of water. This mixture was stirred for one hour at 0° C., followed by stirring for about 2.5 hours at ambient temperature. The mixture was then refrigerated for about 16 hours.
