Participants

Reaction Steps

To a 5 mL round bottom flask was added 3-fluoro-4-(2-(5-((4-methylpiperazin-1-yl)methyl)furan-2-yl)thieno[3,2-b]pyridin-7-yloxy)benzenamine (32 mg, 0.0713 mmol) and 1:1 toluene/ethanol (1 mL). 2-Phenylethanoyl isothiocyanate (25.3 mg, 0.143 mmol; prepared according to the procedure described by J. Org. Chem. 1964, 29, 1115-1119) was added as a solution in toluene (0.5 mL). After stirring for 30 minutes at room temperature, the crude was concentrated in vacuo. The crude was dissolved in MeOH and purified by preparative TLC, eluting with 9:1 CH2Cl2/MeOH. The product was collected at Rf 0.4 just above the unreacted starting material at Rf 0.3 to provide the product (5 mg, 10%) as a white solid. LRMS (APCI+) m/e 626 (M+1) detected; 1H NMR (CDCl3, 400 MHz) δ 9.98 (s, 1H), 8.45 (d, J=5.5 Hz, 1H), 8.22 (s, 1H), 7.75 (d, J=13.7 Hz, 1H), 7.62 (s, 1H), 7.45 (m, 2H), 7.24 (m, 2H), 7.07 (t, J=8.6 Hz, 2H), 6.71 (s, 1H), 6.35 (s, 1H), 3.66 (s, 2H), 2.58 (m, 8H), 2.29 (s, 3H), 1.79 (m, 4H).
