Procedure

Following general procedure IV-2, tert-butyl (4-{[3-acetyl-6-(3-chloro-5-fluoro-4-hydroxyphenyl)-1,5-naphthyridin-4-yl]amino}cyclohexyl)carbamate (0.20 mmol) was reacted with TFA (2 mL) followed by formation of the dihydrochloride salt to afford the desired product (45 mg, 45% over two steps) as a white solid: 1H NMR (500 MHz, D2O) δ 8.99 (s, 1H), 8.13 (d, J=9.0 Hz, 1H), 8.03 (d, J=9.0 Hz, 1H), 7.40-7.34 (m, 2H), 4.91-4.94 (m, 1H), 3.35-3.28 (m, 1H), 2.72 (s, 3H), 2.30-2.22 (m, 2H), 2.21-2.14 (m, 2H), 1.75-1.68 (m, 2H), 1.56-1.48 (m, 2H); ESI MS m/z 429 [M+H]+; HPLC>99% (AUC), tR=9.10 min.
