PROCEDURE
实验过程
Crude (R)-benzyl 2-(6-chloro-3-oxo-1-tosylpyrrolo[4,3,2-de][2,6]naphthyridin-4(1H,3H,5H)-yl)-3,3-dimethylbutanoate was dissolved in MeOH/THF (50%, 5 mL). Aqueous NaOH (1N, 2 mL) was added. The reaction mixture was stirred at 50° C. for 16 h and was purified via preparative mass trigger LC-MS (AcCN/H2O, 20-50%). The fractions were collected, concentrated, and dried in vacuo to afford the title compound as a yellow oil (34 mg, 38.9% from Step A starting material). 1H NMR (400 MHz, CD3OD) δ 1.22-1.32 (m, 9 H) 4.92 (br. s., 1 H) 5.18 (d, J=18.95 Hz, 1 H) 5.33 (d, J=18.95 Hz, 1 H) 7.88 (s, 1 H) 8.29 (s, 1 H). [M+H] calc'd for C15H16ClN3O3, 322; found, 322.5.
