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 1-methyl-3-(R)-amino pyrrolidine dihydrochloride. 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, 12 H) 2.18 (m, 1 H) 2.26 (s, 3 H) 2.32-2.56 (m, 2 H) 2.60-2.68 (m, 2 H) 3.34 (s, 3 H) 3.95 (s, 3 H) 4.07 (t, J=13.52 Hz, 2 H) 4.34-4.54 (m, 2 H) 7.51 (d, J=8.0 Hz, 1 H), 7.54 (br. s., 1 H) 7.90 (s, 1 H), 8.21 (s, 1 H) 8.27 (d, J=8.0 Hz, 1 H) 8.40 (br. s., 1 H). Melting point: 98-99° C. [M+H] calculated for C27H35F2N7O3, 544; found 544.
