Participants

Reaction Steps

Stir a mixture of 3-(4-dimethylaminomethyl-bicyclo[3.2.1]oct-2-en-3-yl)-phenol (200 mg, 0.778 mmol), 2,2-dimethyl-propionyl chloride (111 mg, 0.927 mmol) and triethyl amine (234 mg, 2.316 mmol) in CH2Cl2 (40 mL) at ambient temperature for 12 hours. Concentrate the mixture under vacuum, and purify the residue by Preparative TLC to give 2,2-dimethyl-propionic acid 3-(4-dimethylaminomethyl-bicyclo[3.2.1]oct-2-en-3-yl)-phenyl ester as white solid (232 mg, Yield: 87.5%). MS (m/z): 342 (M+1). 1H NMR (400 MHz, Methanol-d4) δ 7.29-7.32 (t, J=15.6 Hz, 1H), 7.06-7.08 (d, J=7.6, 1H), 6.88-6.90 (d, J1=8.0, J2=1.6, 1H), 6.84-6.85 (t, J=3.6, 1H), 6.05-6.07 (d, J=6.8, 1H), 3.22-3.32 (m, 1H), 2.52-2.60 (m, 1H), 2.62-2.63 (m, 1H), 2.37-2.41 (m, 1H), 2.17 (s, 6H), 2.07-2.14 (m, 1H), 1.71-1.85 (m, 6H), 1.37 (s, 9H).
