실험 절차
To a −78° C. solution of compound 134 (1 g, 3.95 mmol) in ether (20 mL) was added sec-BuLi (1.4 M in hexanes, 0.62 g, 9.67 mmol). The resulting solution was stirred for 30 min at −78° C., followed by addition of acetone (0.91 g, 15.81 mmol) dropwise at −78° C. The reaction mixture was warmed to room temperature overnight. The reaction mixture was partitioned between water and ether and the layers were separated. The aqueous layer was re-extracted with ether. The ether layers were the combined and concentrated in vacuo to yield crude 135 (0.33 g, 55.9%) which was used in the next step without further purification.
