Reaction Steps

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)-2-fluoro-5-methoxybenzoic acid and (R)-tert-butyl 3-aminopiperidine-1-carboxylate as described in the General procedure for amide bond synthesis. The Boc group was then deprotected using TFA. The final compound was purified by reverse phase HPLC and basified to give the free base. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.47 (m, 3 H) 1.61 (m, 9 H) 1.99 (s, 3 H) 2.73 (m, 1 H) 2.93 (m, 1 H) 3.92 (s, 4 H) 4.01-4.20 (t, J=14 Hz, 2 H) 4.82 (m, 1 H) 7.24 (d, J=6.8 Hz, 1 H) 7.71-7.90 (m, 1 H) 8.05 (s, 1 H) 8.14-8.38 (m, 2 H). [M+H] calc'd for C26H32F3N7O3, 548; found 548.
