Reaction Conditions

Reaction Steps

To a mixture of the intermediate 32 (2.99 g, 3.53 mmol) and K2CO3 (0.73 g, 5.29 mmol) in acetone (35 mL) was added 2-bromoethanol (0.38 mL, 5.29 mmol) at rt. After stirring for 15 h at 50° C., the reaction mixture was cooled to rt. The precipitate was removed by filtration and the filtrate was concentrated in vacuo. The residue was dissolved in EtOAc (100 mL), washed with brine, dried over anhydrous MgSO4, filtered and concentrated in vacuo to provide the crude intermediate 33, which was used without further purification (3.04 g, 3.41 mmol, 97%).
