Reaction Steps

2-Aminodibenzthiophene (Bull. Soc. Chim. Fr. (1996), 133 (6), 597-610; 2.0 g, 10 mmol) and triethylamine (1.11 g, 11 mmol) were dissolved in DCM (50 ml) and cooled in an ice bath. A solution of pivaloyl chloride (1.21 g, 10 mmol) in DCM (10 ml) was added slowly and the resultant solution was stirred at ambient temperature for 16 hours then evaporated in vacuo. The residue was triturated with methanol to leave the product as a colourless solid (1.85 g). NMR: 9.40 (s, 1H), 8.59 (s, 1H), 8.17 (m, 1H), 7.98 (d, 1H), 7.90 (d, 1H), 7.73 (dd, 1H), 7.46 (m, 2H), 1.15 (s, 9H); m/z 284.
