Reaction Conditions

Reaction Steps

To a solution of 1,2,3,4-tetrahydro-quinolin-7-ol (200 mg, 1.34 mmol) from step 1 in anhydrous N,N-dimethyl-formamide (5 mL) was added bromomethyl-benzene (229 mg, 1.34 mmol), and potassium carbonate (556 mg, 4.02 mmol). The reaction mixture was stirred at 60° C. overnight. Added some water to the reaction mixture and extracted it with methylene chloride several times. The organic layer was combined, dried over magnesium sulfate, and filtrated. The solution was evaporated under vacuum. The crude residue was purified by MPLC (biotage) to afford 297 mg (93%) of the title compound. 1H-NMR (CDCl3) δ 7.35-7.20 (m, 5H), 6.81 (d, J=8.1 Hz, 1H), 6.05 (dd, J=7.8 Hz, 2.2 Hz, 1H), 5.98 (d, 2.5 Hz, 1H), 4.53 (bs, 1H), 4.44 (s, 2H), 3.34 (t, J=5.0Hz, 2H), 2.73 (t, J=5.8Hz, 2H) 1.98 (m, 2H); MS LC-MS (MH+=240.1), LC MS RT: 3.08 min.
