실험 절차

To a solution of A4 (84 mg, 2 mmol) in 10 mL of DMF, were added the crude 48c from last step and DIEA (2 mL), the reaction mixture was stirred at room temperature overnight. LC/MS was applied to determine completion of the reaction. The reaction mixture was evaporated under reduced pressure and the residue was triturated with 5% diethylamine/methanol (25 mL). The solid was collected by filtration and washed with methanol, dried under vacuum to provide the title compound (58 mg, 62%) as orange solid. 1H NMR (300 MHz, DMSO-d6): δ=13.73 (s, 1H), 10.94 (s, 1H), 8.12-8.15 (d, 1H), 7.73-7.80 (m, 2H), 6.82-6.87 (m, 2H), 5.02-5.05 (q, 1H), 4.58-4.64 (t, 1H), 3.86-4.14 (m, 4H), 3.38-3.44 (m, 2H), 2.42-2.50 (ds, 6H), 1.65-1.88 (m, 4H). LC/MS: 469.0 [M+H]+.
