Yield:615568-24-6 66%

Reaction Conditions:

with manganese(IV) oxide in dichloromethane at 20; for 15 h;

Steps:

7.d

Alcohol (7c) (145mg, 0.87mmol) was dissolved in dichloromethane (5mL) and treated with manganese dioxide (151mg, 1.74mmol). The resulting slurry was stirred at room temperature and after 5 hours a further batch of manganese dioxide (151 mg, 1.74mmol) was added. The slurry was stirred for a further 10 hours and then filtered through Celite and the volatiles removed in vacuo. The residue was purified on silica gel to afford the desired product (95mg, 66%). MS (APCI+) m/z 166 (MH+).
