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 tert-butyl 4-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 1.43 (qd, J=11.9, 3.8 Hz, 2 H) 1.54-1.66 (m, 5 H) 1.66-1.77 (m, 4 H) 1.98 (br. s, 2 H) 2.52 (d, J=1.8 Hz, 2 H) 2.98 (d, J=11.9 Hz, 2 H) 3.79-3.87 (m, 1 H) 3.93 (s, 3 H) 4.04 (t, J=14.2 Hz, 2 H) 4.76 (quin, J=8.1 Hz, 1 H) 7.48 (d, 1 H) 7.50 (s, 1 H) 7.96 (s, 1 H) 8.13 (d, J=8.1 Hz, 1 H) 8.26 (d, J=8.1 Hz, 1 H) 8.26 (s, 1 H). [M+H] calc'd for C26H33F2N7O3, 530; found 530.
