10-Ethyl-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2(7),3,5-trien-4-ylamine (29.8 mg, 0.138 mmol) and 2-(2,5-dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (45 mg, 0.152 mmol, 1.1 eq) were dissolved in IPA (1.5 mL). 4.0 M HCl in dioxane (38 μL, 0.152 mmol, 1.1 eq) was added and the reaction was heated at 130° C. in a microwave for 10 minutes. The reaction was then concentrated under reduced pressure and the residue was taken up in CH2Cl2 (10 mL) and washed with sat. NaHCO3 (10 mL). The organic layer was dried (sodium sulfate), filtered, and concentrated under reduced pressure. Purification by basic alumina chromatography using a gradient of 0-5% MeOH/CH2Cl2 as the eluting solvent to obtain 2-[5-chloro-2-(10-ethyl-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-4-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide as a yellow solid (38 mg, 58%). m.p. dec. at 106° C.; LCMS (m/e) 477 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 11.02 (s, 1H), 8.67 (d, 1H, J=8.4 Hz), 8.09 (s, 1H), 7.50-7.40 (m, 2H), 7.34 (d, 1H, J=2.3 Hz), 7.30-7.20 (m, 1H), 7.02 (t, 1H, J=7.6 Hz), 7.00 (d, 1H, J=7.9 Hz), 6.87 (s, 1H), 6.19 (bs, 1H), 3.03 (d, 3H, 4.9 Hz), 3.00-2.90 (m, 4H), 2.44 (q, 2H, J=7.1 Hz), 2.21-2.16 (m, 4H), 1.64-1.60 (m, 2H), 1.00 (t, 3H, J=7.1 Hz).
