Procedure

N-[trans-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclopentyl]-methanesulfonamide (60 mg, 0.185 mmol), 7-amino-1-ethyl-6-methoxy-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (43 mg, 0.185 mmol) and camphorsulfonic acid (64 mg, 0.278 mmol) were combined in 3 mL isopropanol and heated at 120° C. in microwave for a total of 110 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 39 mg (40%) of a white foam.
