实验过程

Compound 1 (2.00 g, 4.14 mmol) was dissolved in EtOH (40 mL). To this solution was added palladium on carbon (10%, 1.5 g) and cyclohexene (2.5 mL, 24.7 mmol). The reaction mixture was refluxed under argon for 15 hours, filtered through celite and evaporated to give 2 as a slightly impure pale yellow oil (1.50 g, 119%), which was used directly in the next step without further purification. 1H NMR (400 MHz, CDCl3) δ 1.35 (t, J=7.0, 12H), 3.58 (t, J=20.3, 1H), 3.65-3.90 (br s, 2H), 4.20-4.28 (m, 8H).
