実験手順

To 2-iodo-4-oxo-4,5-dihydro-thieno[3,2-c]pyridine-7-carbonitrile 25 (7.75 g, 25.6 mmol) was added POCl3 (90 mL). The reaction was stirred under reflux overnight. POCl3 was removed by rotary evaporation followed by suspension of solids in H2O (500 mL) and filtration. The solids were washed with copious amounts of H2O, saturated bicarbonate solution, and washed further with H2O to provide upon drying 7.52 g of 26. 1H NMR (400 MHz, d6-DMSO) δ 8.82 (s, 1H), 8.06 (s, 1H).
