Reaction Steps

7-Amino-1,3-diethyl-8-methoxy-1,3,4,5-tetrahydro-3-benzazepin-2-one (85 mg, 0.32 mmol;), N-[(1R,2R)-2-(2,5-dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (120 mg, 0.36 mmol), and 10-camphorsulfonic acid (82.5 mg, 0.355 mmol) were charged to isopropyl alcohol (3 ml, 40 mmol) in a microwave reaction tube. The reaction was heated in microwave at 120° C. for 40 minutes. The resulting solution was poured into a mixture of 20 ml saturated sodium bicarbonate solution and 40 ml water and the aqueous solution was extracted with methylene chloride (4×10 ml portions). The combined organic extracts were dried over magnesium sulfate, filtered and evaporated under reduced pressure to yield a clear yellow oil. The oil was evaporated onto celite and the celite placed on silica gel (12 g Isco column) and eluted with 0-70% EtOAc in Hexanes to obtain N-{(1R,2R)-2-[5-Chloro-2-(1,3-diethyl-8-methoxy-2-oxo-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide as a beige powder.
