Reaction Steps
1-Methoxy-N*7*-(2-methoxy-ethyl)-6,7,8,9-tetrahydro-5H-benzocycloheptene-2,7-diamine 200 mg, 0.8 mmol) and (1S,2S,3R,4R)-3-(2,5-dichloro-pyrimidin-4-ylamino)-bicyclo[2.2.1]hept-5-ene-2-carboxylic acid amide (224 mg, 0.750 mmol) were dissolved in 5 ml 2-methoxyethanol in a reaction tube. 4N HCl in dioxane (0.4 ml, 1.6 mmol) was charged and the reaction heated to 130° C. The reaction was followed by HPLC. Upon completion, the reaction was poured into saturated sodium bicarbonate (50 ml) and extracted with methylene chloride (4×25 ml portions). The combined organic was dried over magnesium sulfate, filtered and evaporated. Purification was carried via preparative HPLC and the desired fractions neutralized and extracted to yield (1S,2S,3R,4R)-3-{5-Chloro-2-[1-methoxy-7-(2-methoxy-ethylamino)-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino]-pyrimidin-4-ylamino}-bicyclo[2.2.1]hept-5-ene-2-carboxylic acid amide (58.19 mg, 27% yield) as the beige foam free base. Purification separated the compound into its corresponding enantiomers. 1H-NMR (CDCl3) δ 8.17 (d, J=8.3 Hz, 1H), 7.88 (s, 1H), 7.39 (s, 1H), 6.94 (m, 1H), 6.86 (d, J=8.4 Hz, 1H), 6.37 (m, 1H), 6.31 (m, 1H), 5.61 (br s, 1H), 5.36 (br s, 1H), 4.37 (m, 1H), 3.72 (s, 3H), 3.51 (m, 2H), 3.26 (s, 3H), 3.23 (m, 1H), 3.06 (s, 1H), 2.94 (s, 1H), 2.85-2.70 (m, 6H), 2.49 (d, J=8.4 Hz, 2H), 2.24 (d, J=8.9 Hz, 1H), 2.09 (m, 2H), 1.63 (m, 2H), 1.26 (m, 4H).
