cis-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclopentanecarboxylic acid methylamide (46 mg, 0.160 mmol), 2-(7-amino-8-methoxy-1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-N,N-dimethyl-acetamide (44 mg, 0.160 mmol) and camphorsulfonic acid (56 mg, 0.240 mmol) were combined in 3 mL isopropanol and heated at 120° C. in microwave for a total of 90 min. The reaction was concentrated to be taken up in dichloromethane and washed with saturated sodium bicarbonate solution (2×30 mL). The organic layer was dried over MgSO4 and filtered. The filtrate was chromatographed on a 4 g amine capped ISCO flash column from 0-100% ethyl acetate in hexanes. The product was collected as a foam after concentrating to afford 43 mg (51%) of a white foam.
