Reaction Steps

The ethyl 8-(iodomethyl)-6-methyl-2-(trifluoromethyl)-2H-chromene-3-carboxylate prepared as in Example 605e, Step 2 (0.2 g, 0.47 mmole) was dissolved in methanol (5 mL) and the solution was cooled to 0° C. (ice bath). Sodium ethoxide (0.10 g, 1.41 mmole) was added dropwise to the above solution, which was stirred for 2 hours at 0° C. The solution was warmed to room temperature and stirred for an additional 2 hours. The reaction was condensed in vacuo to give a yellow oil (0.16 g, 98%). No further purification was performed: GCMS m/z 344.00 (M+).
