Conditions

Temperature: 80 °C

Procedure

Compound A2 (0.13 mmol, 50 mg), and ethyl chloroformate (0.13 mmol, 13 μL) were dissolved in DMF (1 mL) and triethylamine (0.36 mmol, 50 μL). The reaction was heated in a microwave at 80° C. for 4 minutes. The mixture was quenched with water and extracted with ethyl acetate. Removal of organic solvent in vacuo provided Compound A10 as a yellow solid (50 mg, 89%). 1H NMR (400 MHz, CDCl3) δ (ppm): 9.97 (s, 1H), 8.20 (s, 1H), 7.77 (d, 2H), 7.66 (d, 2H), 5.41 (heptet, 1H), 3.96 (q, 2H), 3.47 (m, 4H), 2.88 (s, 3H), 1.72 (m, 4H), 1.08 (t, 3H). LCMS (ESI), m/z 466.3 (M+H+, 100%).
