Procedure

2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (86.3 mg, 0.290 mmol) and N*7*-(2,2,2-trifluoro-ethyl)-6,7,8,9-tetrahydro-5H-benzocycloheptene-2,7-diamine (75 mg, 0.290 mmol) were combined with DL-10-camphorsulfonic acid (101 mg, 0.436 mmol) in 2 ml IPA and heated in a microwave vial for 40 minutes at 120° C. for 40 minutes. The resulting reaction was poured into 25 ml saturated sodium bicarbonate solution and 50 ml water and extractred with 4×25 ml portions of methylene chloride. The combined organic was dried over magnesium sulfate, filtered and evaporated. The crude product was purified via reverse phase preparative chromatography (Luna C18, 5 μm, 100 mm×21.2 mm column) using a gradient of 0-35% MeCN in water (both containing 0.1% TFA). 2-{5-Chloro-2-[7-(2,2,2-trifluoro-ethylamino)-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino]-pyrimidin-4-ylamino}-N-methyl-benzamide (11.18 mg, 7.4% yield) was isolated as an off white solid. 1H-NMR (CDCl3) δ 11.07 (s, 1H), 8.66 (d, J=8.44 Hz, 1H), 7.45 (m, 2H), 7.35 (s, 1H), 7.04 (m, 2H), 6.91 (s, 1H), 6.18 (s, 1H), 3.24 (q, J=19.4, 9.8 Hz, 2H), 3.03 (d, J=4.8 Hz, 3H), 2.87 (m, 3H), 2.66 (m, 2H), 2.06 (m, 2H), 1.32 (m, 5H). LC/MS (ESI+)=519 (M+H). MP=202-203° C.
