64% With formaldehyd; In acetonitrile; 5-(4-Methyl-5-nitroindol-3-ylmethyl)-2,2-dimethyl-1,3-dioxane-4,6-dione An adaption of the procedure of Flaugh was used. Thus, a solution of <strong>[165250-69-1]4-methyl-5-nitroindole</strong> (0.880 g, 5.00 mmol), Meldrum's acid (0.864 g, 6.00 mmol), 37% aqueous formaldehyde (0.5 mL, 6.0 mmol) and D,L-proline (0.029 g, 0.25 mmol) in 25 mL of acetonitrile was stirred at room temperature for 72 h. The resulting yellow slurry was stored at -20 C. and then the cold mixture was filtered. The filtercake was washed with cold acetonitrile and ether, and then it was dried in vacuo to give the title compound (1.055 g, 64%) as a canary-yellow solid, mp 196-198 C.

After cooling the reaction mixture to room temperature, water and 1 mL of 1 mol/L hydrochloric acid were added thereto dropwise, and the solvent was distilled off under reduced pressure. After adding ethyl acetate and water, the organic layer was separated, washed with a saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to give 172 mg of 6-fluoro-5-nitro-1H-indole as a yellow brown solid. 1H-NMR (DMSO-d6) delta: 6.71 (1H, s), 7.47 (1H, d, J = 11.9 Hz), 7.60 (1H, s), 8.48 (1H, d, J = 7.3 Hz), 11.82 (1H, s).
