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)-1-aminopropan-2-ol. The final compound was purified by reverse phase HPLC and basified to give the free base. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.07 (d, J=6.1 Hz, 3H) 1.12-1.41 (m, 3H) 1.55-1.87 (m, 8H) 1.70-1.88 (m, 4H) 3.21 (q, J=6.3 Hz, 1H) 3.32 (s, 3H) 3.77 (m, 1H) 3.94 (s, 3H) 4.16 (t, J=13.0 Hz, 2H) 4.49 (quin., J=12.1 Hz, 1H) 7.53 (d, J=8.6 Hz, 1H) 7.58 (s, 1H) 8.14 (d, J=8.3 Hz, 1H) 8.23 (s, 1H) 8.41-8.47 (m, 1H) 8.51-8.57 (m, 1H).
