実験手順

Compound 43a (176 mg, 1.0 mmol) was dissolved in 8 mL of CH2Cl2 and 4 mL of TFA (containing 5% H2O) was added. The mixture was stirred for 30 min at room temperature. The solution was then concentrated in vacuo to give the product 44a that was used immediately for the next step. 1H NMR (400 MHz, CDCl3) δ 0.92 (m, 3H), 1.64 (m, 2H), 2.24 (t, J=7.04 Hz, 2H), 4.72 (s, 2H), 9.60 (s, 1H).
