Nitration of N ‐(trifluoroacetyl)‐L‐tryptophan methyl ester provides 40% of the anticipated 6‐nitro product and 6–7% of the novel 2‐nitro derivative. The latter compound is deprotected with aqueous acid to form 2‐nitro‐L‐tryptophan. Analogous nitration of L‐tryptophan gives only the 6‐nitro product.
