実験手順

A solution of 1-(tert-butoxycarbonyl)-4-methylpiperidine-4-carboxylic acid (0.830 g, 3.41 mmol) and triethylamine (0.792 mL, 5.68 mmol) in DMF (11.0 mL) was treated with TFFH (1.13 g, 4.26 mmol). The resulting mixture was stirred at rt for 30 min and then methyl 1,2,3,4-tetrahydroisoquinoline-6-carboxylate hydrochloride (0.647 g, 2.84 mmol) and triethylamine (0.792 mL, 5.68 mmol) were added. The reaction mixture was stirred at rt for 2 days and then extracted with EtOAc three times. The combined organic phases were washed with water and brine, dried over Na2SO4, filtered and concentrated. Purification of the resulting residue by column chromatography (SiO2, 0-100% EtOAc in hexane) provided methyl 2-{[1-(tert-butoxycarbonyl)-4-methylpiperidin-4-yl]carbonyl}-1,2,3,4-tetrahydroisoquinoline-6-carboxylate (0.959 g, 82%). LC-MS: (FA) ES+ 439 (M+Na); 1H NMR (400 MHz, CDCl3) δ 7.85 (dd, J=10.1, 2.2 Hz, 2H), 7.19 (d, J=8.0 Hz, 1H), 4.79 (s, 2H), 3.95-3.77 (m, 5H), 3.67 (d, J=38.1 Hz, 2H), 3.21 (s, 2H), 2.92 (t, J=5.7 Hz, 2H), 2.24-2.10 (m, 2H), 1.61 (d, J=10.8 Hz, 1H), 1.44 (d, J=5.0 Hz, 10H), 1.33 (d, J=3.6 Hz, 3H).
