Reaction Steps

3-(2-Methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (76 mg, 0.34 mmol, 1.0 eq), 2-(2,5-dichloro-pyrimidin-4-ylamino)-3,N-dimethyl-benzamide (118 mg, 0.38 mmol, 1.1 eq), and 10-camphorsulfonic acid (88 mg, 0.38 mmol, 1.1 eq) were dissolved in IPA (3 mL) and heated at 120° C. in a microwave for 40 minutes. The reaction was then concentrated under reduced pressure and the residue was taken up in CH2Cl2 (20 mL) and washed with sat NaHCO3 (20 mL). The organic layer was dried (sodium sulfate), filtered, and concentrated under reduced pressure. Purification by amine capped silica gel chromatography using a gradient of 0-100% EtOAc/hex as the eluting solvent to obtain 2-{5-chloro-2-[3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-3,N-dimethyl-benzamide as a pale yellow foam (50 mg, 30%).
