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)-(−)-3-aminoquinuclidine. The final compound was purified by reverse phase HPLC and basified to give the free base. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.10-1.42 (m, 3 H) 1.57-1.92 (m, 12 H) 2.71-89 (m, 4 H) 2.96 (m, 1 H) 3.13 (m, 1 H) 3.31 (s, 3 H) 3.95 (s, 3 H) 3.97-4.10 (m, 2 H) 4.45 (m, 1 H) 7.47 (d, J=8.0 Hz, 1 H) 7.50 (s, 1 H) 7.93 (s, 1 H) 8.19 (d, 1 H) 8.21 (s, 1 H) 8.26 (d, J=8.0 Hz, 1 H). [M+H] calculated for C29H37F2N7O3, 570; found 570.
