Методика

To a mixture of N-(3-hydroxy-4-tert-butyl-phenyl)-4-oxo-1H-quinoline-3-carboxamide (428) (6.7 mg, 0.02 mmol) and Cs2CO3 (13 mg, 0.04 mmol) in DMF (0.2 mL) was added BnBr (10 uL, 0.08 mmol). The reaction mixture was stirred at room temperature for 3 h. The reaction mixture was filtered and purified using HPLC to give 4-benzyloxy-N-(3-hydroxy-4-tert-butyl-phenyl)-quinoline-3-carboxamide (275). 1H NMR (400 MHz, DMSO-d6) δ 12.23 (s, 1H), 9.47 (s, 1H), 9.20 (s, 1H), 8.43 (d, J=7.9 Hz, 1H), 7.79 (t, J=2.0 Hz, 2H), 7.56 (m, 1H), 7.38-7.26 (m, 6H), 7.11 (d, J=8.4 Hz, 1H), 6.99 (dd, J=8.4, 2.1 Hz, 1H), 5.85 (s, 2H), 1.35 (s, 9H). HPLC ret. time 3.93 min, 10-99% CH3CN, 5 min run; ESI-MS 427.1 m/z (MH+).
