Using a similar procedure to that described in Example 1, part d, except starting from methyl 4-(5-formyl-1-methylindol-3-ylmethyl)-3-methoxybenzoate and N-methylpyrrolidone, methyl 4-[5-[(hydroxy)-(1-methyl -2-oxopyrrolidin-3-yl)methyl]-1-methylindol-3-ylmethyl]-3-methoxybenzoate was obtained (40%) as a foam; NMR (300 MHz, DMSO-d6): 1.43-1.65 (m, 1.5H), 1.95 (m, 0.5H), 2.40-2.60 (m, 2.5H), 2.65-2.80 (m, 2H), 2.90-3.25 (m, 1.5H), 3.70 (s, 3H), 3.83 (s, 3H), 3.85-4.08 (m, 5H), 4.92 (d, 0.5H), 5.17 (s, 0.5H), 7.0-7.55 (m, 7H).
