Procedure

The title compound was synthesized from 4-(9-Cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[5,4-b][1,4]diazepin-2-ylamino)-3-methoxybenzoic acid as described in the General procedure for amide bond synthesis using HATU and (S)-tert-butyl 3-aminopiperidine-1-carboxylate, where Boc was removed using TFA in DCM. The final compound was purified by reverse phase HPLC and basified to give the free base. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.41-1.52 (m, 2 H) 1.52-1.77 (m, 7 H) 1.85-1.99 (m, 3 H) 2.45 (t, J=9.9 Hz, 2 H) 2.85 (d, J=12.4 Hz, 1 H) 3.01 (dd, J=11.8, 3.4 Hz, 1 H) 3.32 (s, 3 H) 3.85 (m, 1 H) 3.94 (s, 3 H) 4.05 (t, J=14.0 Hz, 3 H) 4.76 (quin, J=8.2 Hz, 1 H) 7.47 (dd, J=1.8 Hz, 1 H) 7.49 (s, 1 H) 7.97 (s, 1 H) 8.04 (d, J=7.8 Hz, 1 H) 8.26 (s, 1 H) 8.28 (d, 1 H). [M+H] calc'd for C26H33F2N7O3, 530; found 530.
