The neat reaction mixture was subsequently stirred at 45 °C for 48 h. To the mixture was added a sat. aq solution of NH4Cl (20 mL) and the organic and the aqueous layer were separated. The latter was extracted with CH 2Cl2 (3 × 20 mL, The combined organic layers were dried (Na2SO4, filtered and the filtrate was concentrated in vacuo. The residue was purified by chromatography (silica gel, heptanes-EtOAc) to give 14.
