Reaction Steps

To a solution of methyl 1,2,3,4-tetrahydroisoquinoline-6-carboxylate hydrochloride (500.0 mg, 2.00 mmol) in DMF (17.0 mL) was added 4-bromobenzylbromide (604 mg, 2.42 mmol) and K2CO3 (910 mg, 6.59 mmol). The resulting mixture was stirred overnight at rt. EtOAc and water were added, and the phases were separated. The organic phase was dried over Na2SO4, filtered and concentrated. The resulting residue was purified by column chromatography (SiO2, 0-40% EtOAc in hexane) to give methyl 2-(4-bromobenzyl)-1,2,3,4-tetrahydroisoquinoline-6-carboxylate (753 mg, 100%). LC-MS: (FA) ES+ 361; 1H NMR (300 MHz, CDCl3) δ 7.86-7.70 (m, 2H), 7.46 (dd, J=8.7, 2.1 Hz, 2H), 7.36-7.21 (m, 2H), 7.04 (d, J=8.0 Hz, 1H), 3.89 (d, J=3.8 Hz, 3H), 3.64 (s, 4H), 2.93 (t, J=5.8 Hz, 2H), 2.83-2.64 (m, 2H).
