Yield:873054-44-5 76%
Reaction Conditions:
with water;sodium hydroxide in methanol at 20; for 5 h;
Steps:
                    28 Example 28: Synthesis of ivacaftor (26):
To a solution of 2,4-di-tert-butyl-5-(4-oxo-1,4-dihydroquinoline-3-carboxamido)phenyl methyl carbonate 5 (30 mg, 0.06mmol) in MeOH (2 mL) was added NaOH (5.3 mg, 0.13mmol) dissolved in H2O (2 mL), and the reaction mixture was stirred at room temperature for 5h. Reaction mass was evaporated to one third of its volume (temperature not exceeding 40°C) and acidified with aq.2N HC1 to pH 2-3. The resulting precipitate was collected by suction filtration give desired compound 7 (19 mg, 76%) as off white solid. 1H NMR (400MHz, DMSO-d6) δ = 12.88 (d, J = 6.6 Hz, 1 H), 11.81 (s, 1 H), 9.20 (s, 1 H), 8.86 (d, J = 6.6 Hz, 1 H), 8.32 (d, J = 7.8 Hz, 1 H), 7.88 - 7.65 (m, 2 H), 7.51 (t, J = 7.5 Hz, 1 H), 7.16 (s, 1 H), 7.10 (s, 1 H), 1.38 (s,9H), 1.36 (s, 9H).
