Procedure

The title compound was synthesized from 4-(9-cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-ethylbenzoic acid as described in the General procedure for amide bond synthesis using HATU and 1-methylpiperidin-4-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 1.14 (t, J=8.0 Hz, 3 H) 1.23-1.69 (m, 11 H) 1.77 (m, 4 H) 1.99 (m, 2 H) 2.20 (s, 3 H) 2.69 (q, J=7.3 Hz, 2 H) 3.75 (s, 1 H) 3.97 (t, J=14.2 Hz, 2 H) 4.54 (t, J=8.1 Hz, 1 H) 7.57-7.81 (m, 3 H) 8.12 (d, J=7.8 Hz, 1 H) 8.17 (s, 1 H) 8.61 (s, 1 H). [M+H] calc'd for C28H37F2N7O2, 542; found 542.
