Procedure

A solution of (E) (0.56 g.) in tetrahydrofuran (30 ml.) was hydrogenated in the presence of palladium-on-carbon (10% w/w: 0.1 g.), as described for the amino ester (A) in Example 1, to give methyl 4-(5-amino-1-methylindol-3-ylmethyl)-3-methoxybenzoate (D) (0.50 g., 98%) as pale yellow foam: NMR: 3.6(s, H, NCH3), 3.8(s,3H, CO.OCH3), 3.9(br s,5H, OCH3 and CH2.Ar), 4.45(br,2H, NH2), 6.54(m,2H), 6.86(s,1H), 7.04(m,2H), 7.40(m,2H).
