1.40 g (3.8 mmol) of the ester produced in Example 13, are dissolved in 20 ml of dry THF, and treated with 0.14 g (4.6 mmol) of sodium hydride (80% in oil). This mixture is stirred for 1 hour, at which point 0.65 g (4.4 mmol) of methyl iodide is added. The resulting mixture is stirred for 2 hours and then poured into water (100 ml) and extracted with dichloromethane (3×100 ml). The organic phase is dried and the solvent evaporated. The resulting residue is recrystallized in hexane, yielding methyl 1-methyl-2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)-6-indole carboxylate. (1.30 g, 91%)
