Pyridine → 2-adamantyl Chloroformate

참여 물질

반응 단계

To a solution of 2-adamantanol (912 mg, 5.99 mmol) in methylene chloride (15 mL), at 0° C. under nitrogen, was added a solution of triphosgene (653 mg, 2.2 mmol) and pyridine (484 μL, 5.99 mmol) in methylene chloride. The reaction mixture was stirred at ambient temperature for 3 hours and then concentrated to dryness under reduced pressure. Ethyl acetate was added to the residue and the resultant mixture was filtered. The filtrate was concentrated in vacuo to give 980 mg of the title compound as a white powder. 1H NMR (CDCl3) δ1.5-2.2 (m, 14H), 5.02 (m, 1H).
