Reaction Steps

A mixture of 29 g of tryptamine and 30 g of 3-methoxy-phenylacetic acid was heated at 200° C. for one hour and after cooling the mixture to 50° C., the mixture was dissolved in 200 ml of ethyl acetate. The organic phase was washed successively with N hydrochloric acid, with water, with 2 N sodium hydroxide and with water and was dried and evaporated to dryness. The 59 g of red oil were crystallized from ether and the mixture was vacuum filtered. The product was dried to obtain 47.2 g of 3-methoxy-N-[2-(1H-indol-3-yl)-ethyl]-benzeneacetamide in the form of a beige solid melting at 78° C. which was used as is for the next step. A sample recrystallized from ether melted at 82° C.
