60% Sodium hydride dispersion in mineral oil (90 mg, 2.25 mmol) was added to a stirred, cooled solution of 7-cyanomethoxyindole (Example 1a) (0.32 g., 1.86 mmol) in tetrahydrofuran (8 ml). The dark mixture was stirred for 15 minutes at room temperature then cooled again whilst a solution of 3-(1,3-dioxolan-2-yl)benzyl bromide (0.50 g., 2.06 mmol) in tetrahydrofuran (2 ml) was added. The mixture was stirred at room temperature for 20 hours then treated with glacial acetic acid (130 μl), diluted with dichloromethane, washed with water, dried and evaporated. The residue was chromatographed on silica in ethyl acetate-hexane (1:3).
