Reaction Steps

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 4-amino piperidine 1-ethanol. The final compound was purified by reverse phase HPLC and basified to give the free base. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.44-2.07 (m, 12 H) 2.38 (t, J=6.32 Hz, 2 H) 2.89 (d, J=11.37 Hz, 2 H) 3.27-3.34 (s, 3 H) 3.49 (q, J=6.06 Hz, 2 H) 3.65-3.83 (m, 1 H) 3.93 (s, 2 H) 3.97-4.14 (m, 2 H) 4.37 (t, J=5.31 Hz, 1 H) 4.76 (t, J=7.83 Hz, 1 H) 7.48 (d, J=8.0 Hz, 1 H), 7.49 (br. s., 1 H) 7.96 (s, 1 H) 8.12 (d, J=7.83 Hz, 1 H)), 8.26 (s, 1 H) 8.27 (d, J=8.0 Hz, 1 H). [M+H] calculated for C28H37F2N7O4, 574; found 574.
