実験手順

To a solution of 2-bromo-3-hydroxymethylthiophene from Example 1, Step 1 (13.0 g, 67.3 mmol) in THF (100 mL) and water (10 mL) was added N-chlorosuccinimide (9.88 g, 74.0 mmol) and the mixture was stirred at r.t. for 5 h and concentrated in vacuo. The residue was worked up as above to afford the desired product. The crude product was used directly.
