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 piperidin-1-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 1.15-1.90 (m, 16 H) 3.16 (br. s., 6 H) 3.32 (s, 3 H) 3.96 (s, 3 H) 4.14 (t, 2 H) 4.48 (quin, 1 H) 7.47 (d, 1 H) 7.49 (s, 1 H) 8.22 (d, 1 H) 8.24 (s, 1 H) 8.47 (br. s., 1 H). [M+H] calc'd for C27H35F2N7O3 544; found 544.
