The reaction was stirred overnight under N2. The reaction mixture was then diluted with CH2Cl2 (50 mL), washed with water (2×15 mL), and saturated NaCl (15 mL). Dried over MgSO4, filtered, and concentrated to give compound 2 (3.7 g). This crude material was used in subsequent reactions without further purification.
