55750-48-6, 2-([2,2?:6?,2??-terpyridin]-4?-yloxy)ethylamine (3) (290 mg,1.0 mmol) in 40 mL of acetone/water (2/1) was added to a solutionof NaHCO3 (440 mg, 5.3 mmol) and N-methoxycarbonylmaleimide (4)(470mg, 3.0mmol) at 4 C, and the reaction mixturewas stirred for 1 h.The solution was added to water (6 mL) and stirred for 2 h at roomtemperature. The obtained precipitate was collected and washed withwater. The product was recrystallized from acetone/water (4/1).Yield: 220 mg (58%); 1H NMR (400 MHz, CDCl3) delta 8.74 (d, J = 4.8 Hz,2 H), 8.61 (d, J = 8.0 Hz, 2 H), 8.11 (s, 2 H), 7.97 (dd, J = 8.0, 7.5,1.9 Hz, 2 H), 7.44 (dd, J = 7.5, 4.8 Hz, 2 H), 6.75 (s, 2 H), 4.50 (t, J =5.6 Hz, 2 H), 4.05 (t, J = 5.6 Hz, 2 H). 13C NMR (100 MHz, CDCl3) delta170.34, 166.57, 156.78, 155.53, 148.71, 137.21, 134.26, 124.01, 121.54,107.59, 64.86, 36.94.
