Participants

Reaction Steps

The crude product from (iii) above (5.62 g, 18.84 mmol) and triethylamine (2.6 mL, 18.7 mmol) were dissolved in chloroform (90 mL) and cooled in an ice bath. A solution of chloroacetyl chloride (1.5 mL) in chloroform (40 mL) was added dropwise with stirring. After the completion of the addition, the solution was stirred in the ice bath for 15 minutes and warmed to ambient temperature and stirred for 20 hours. The solution was washed with water (4×80 mL). Drying (MgSO4) and concentration yielded the product (6.71 g, 93%) which was used without further purification. 1H NMR (CDCl3, δ): 7.95 (d), 6.87 (d), 6.54 s, br), 4.01 (d), 3.96 (t), 3.86 (s), 3.28 (q), 1.76 (m), 1.55 (m), 1.45 (m), 1.29 (m). 13C NMR (CDCl3, δ): 130.71, 130.66, 121.52, 113.23, 75.37, 67.33, 50.95, 41.85, 39.04, 28.56, 28.53, 28.47, 28.43, 28.33, 28.25, 25.94, 25.11.
