Procedure

To a suspension of Compound 14c (5.05 g; 20.59 mmol) in DMF (70 mL) was added SOCl2 (3 mL; 41.23 mmol) dropwise at room temperature. The reaction was stirred at room temperature for 30 min, then poured into an ice water slurry of K2CO3 (3.41 g). The resultant solid (Compound 14d) was collected by filtration and dried. 1H NMR (300 MHz, CDCl3): δ 9.70 (s, 1H), 9.20 (s, 1H), 7.70-8.85 (m, 2H), 7.50 (dd, 1H), 4.50 (q, 2H), 1.45 (t, 3H); MS: m/z 264.1 (M+H)+.
