The reaction mixture was diluted with DMF (3 mL) and K2CO3 (5 mmol, 0.690 g) was added. The reaction mixture was then heated at 80°C for 3 h and was allowed to cool to r.t. Saturated aq NaCl soln (5 mL) was added and extracted with CH2Cl2 (5 x 10 mL, The combined organic layer was dried over anhyd Na2SO4. Solvent was evaporated, and the residue, thus obtained, was purified by column chromatography (SiO 2, 5% EtOAc in hexanes) to furnish the pure compound 2a as a colorless solid.
