Hydrochloric Acid → HCID 86592155, compound

Participants

Reaction Steps

To a mixture of (R)-1-benzyloxy-3-pentylazetidin-2-one (0.96 g, 3.89 mmol) in a mixture of THF-H2O-MeOH (50 mL, 3:1:1 v/v) was added lithium hydroxide monohydrate (1.91 g, 38.9 mmol). After stirring at room temperature overnight, water (25 mL) was added to the mixture. The solution was acidified to pH 5˜6 with 3N aqueous HCl solution. It was extracted with EtOAc (50 mL×2). The combined organic layers were dried over MgSO4. Removal of the solvent under vacuum provided the title compound. 1H NMR (400 MHz, CHCl3) δ 9.80 (br s, 1H), 7.37 (m, 5H), 4.75 (m, 2H), 3.14 (m, 2H), 2.74 (m, 1H), 1.70 (m, 1H), 1.53 (m, 1H), 1.38-1.25 (m, 6H), 0.91 (t, J=6.8 Hz, 3H). MH+266.
