実験手順

To the styrene of Step 1 (0.310 g, 1.3 mmol) in 5 mL of THF was added 1 M LiAlH4 solution in THF (5.2 mL, 5.2 mmol) at 0° C. The solution was stirred for 1 hour. A concentrated KHSO4 solution was added dropwise to destroy the excess of LiAlH4. The solution was filtered over celite and the filtrate concentrated in vacuo to give a yellow oil; 150 mg (58%).
