実験手順

A solution of 120a (6.9 g, 29 mmol) in chloroform (50 mL) was added over 2 h to POCl3 (9.9 g) with heating under reflux. After 2.7 h additional reflux, the mixture was cooled in an ice bath, and filtered to remove a white precipitate. The filtrate was neutralized by extraction with saturated aqueous NaHCO3 and chloroform. The organic phase was dried (Na2SO4), filtered, and evaporated no an oil (5.4 g). IR(neat): cm-1 1720. 1H NMR(300 MHz, CDCl3): 7.42-6.87 (m, 4H), 3.90(s, 3H), 3.77 (t, 4H, J=7 Hz), 3.64 4H, J=7 Hz). HR-MS: Calc'd. 276.0558, Found 276.0553.
