Trimethylsilyldiazomethane → Methyl 4-pentylbicyclo[2.2.2]octane-1-carboxylate

Participants

Reaction Steps

(Trimethylsilyl)diazomethane (2M/hexane, 53 mL, 106 mmol) was added slowly to a solution of 4-pentylbicyclo[2.2.2]octane-1-carboxylic acid (2-A) (20.3 g, 90.6 mmol) in methylene chloride (100 mL) and methanol (40 mL) until the yellow color persisted. After stirring for 10 min at room temperature, the solution was concentrated in vacuo to give methyl 4-pentylbicyclo[2.2.2]octane-1-carboxylate (2-B). 1H NMR (500 MHz, CDCl3): δ 0.89 (t, 3H); 1.20 (m, 8H); 1.39 (m, 6H); 1.77 (m, 6H); 3.65 (s, 3H) ppm.
