Reaction Steps

The title compound was synthesized from 4-(9-cyclohexyl-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)-1-methylpiperidin-3-amine. The final compound was purified by reverse phase HPLC and basified to give the free base. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.17-1.26 (m, 2 H) 1.29-1.46 (m, 3 H) 1.55-1.73 (m, 5 H) 1.75-1.90 (m, 6 H) 2.23 (br s, 3 H) 2.64-2.78 (m, 1 H) 2.79-2.95 (m, 1 H) 3.31 (s, 3 H) 3.90-4.01 (m, 1 H) 3.94 (s, 3 H) 4.07 (t, J=12.63 Hz, 2 H) 4.37-4.53 (m, 1 H) 7.47 (dd, J=8.46, 1.64 Hz, 1 H) 7.51 (d, J=1.77 Hz, 1 H) 7.91 (s, 1 H) 8.10 (d, J=7.33 Hz, 1 H) 8.21 (s, 1 H) 8.27 (d, J=8.34 Hz, 1 H). [M+H] calc'd for C28H37F2N7O3 558; found 558.
