To a solution of (R)-2-(6-chloro-3-oxo-1-tosylpyrrolo[4,3,2-de][2,6]naphthyridin-4(1H,3H,5H)-yl)-3-cyano-N-cyclopentylpropanamide in MeOH (2 mL) was added aqueous NaOH (1N, 0.5 mL). The reaction mixture was stirred for 20 min and the product was purified via preparative mass trigger LC-MS (AcCN/H2O, 5-50%). The fractions were collected, concentrated, and dried in vacuo to afford the title compound as a yellow oil (0.5 mg, 2.1% from Step A starting material). 1H NMR (400 MHz, CD3OD) δ 1.37-1.72 (m, 4H) 1.83-1.95 (m, 4 H) 3.22-3.26 (m, 2 H) 3.69-3.76 (m, 1 H) 5.11 (s, 1 H) 5.14-5.17 (m, 1 H) 5.18 (s, 1 H) 7.88 (s, 1 H) 8.27 (s, 1 H). [M+H] calc'd for C18H18ClN5O2, 372; found, 372.4.
