Procedure

Following general procedure I, cyclopropyl(4,6-dichloro-1,5-naphthyridin-3-yl)-methanone (267 mg, 1.0 mmol) was reacted with (S)-tert-butyl 1-(5-aminopyridin-2-yl)-piperidin-3-ylcarbamate (340 mg, 1.2 mmol) to afford the desired product (329 mg, 63%) as a brown solid: 1H NMR (500 MHz, CDCl3) δ 10.19 (br s, 1H), 9.03 (s, 1H), 8.17 (d, J=8.8 Hz, 1H), 8.04 (d, J=2.8 Hz, 1H), 7.53 (d, J=8.8 Hz, 1H), 7.31-7.25 (m, 1H), 6.70 (d, J=9.1 Hz, 1H), 4.78 (br s, 1H), 3.83-3.62 (m, 3H), 3.47-3.25 (m, 2H), 2.55-2.47 (m, 1H), 1.97-1.83 (m, 2H), 1.73-1.58 (m, 1H), 1.45 (s, 9H), 1.12-1.04 (m, 2H), 1.00-0.90 (m, 2H); ESI MS m/z 523 [M+H]+
