Procedure

Prepared analogously to Example 216d replacing 3-Ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine with 2-Amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-7-ol and (2,5-Dichloro-pyrimidin-4-yl)-[2-(1-methyl-1H-imidazol-2-yl)-phenyl]-amine was replaced with (1S,2S,3R,4R)-3-(2,5-Dichloro-pyrimidin-4-ylamino)-bicyclo[2.2.1]hept-5-ene-2-carboxylic acid amide. 2-Amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-7-ol is a byproduct from the reductive amination of 2-Nitro-5,6,8,9-tetrahydro-benzocyclohepten-7-one with various amines. The reaction was carried out in the presence of the desired reductive amination product to provide a crude mixture of amino and alcohol products. The crude mix was then reduced and a mixture of amino and alcohol products were used in the synthesis of target compounds. The mixture was then purified by prep HPLC to afford the desired amino compound as well as (1S,2S,3R,4R)-3-[5-Chloro-2-(7-hydroxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-bicyclo[2.2.1]hept-5-ene-2-carboxylic acid amide. LC/MS (ESI): 440.22. 1H NMR (400 MHz, DMSO, d6) δ 9.12 (s, 1H), 7.93 (s, 1H), 7.78 (s, 1H), 7.69 (m, 1H), 7.46 (m, 2H), 7.26 (s, 1H), 6.97 (d, 1H, J=8.08 Hz), 6.35 (m, 1H), 6.27 (m, 1H), 4.58 (m, 1H), 4.15 (m, 1H), 3.72 (m, 1H), 3.31 (s, 2H), 2.88 (s, 1H), 2.78 (m, 3H), 2.11 (d, 1H, J=8.59 Hz), 1.89 (m, 2H), 1.41 (d, 1H, J=8.09 Hz), 1.33 (m, 2H).
