The title compound was prepared from 1,4-Diethyl-2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepin-8-ylamine (0.105 g, 0.000407 mol), 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N,N-dimethyl-benzenesulfonamide (0.140 g, 0.000403 mol), 10-camphorsulfonic acid (0.237 g, 0.0010 mol) and isopropyl alcohol (4 mL). The mixture was heated in a microwave at 100° C. for 20 min. After evaporation of the solvent, the residue was treated with a 10% sodium carbonate solution/DCM, separated, washed, dried and evaporated to give a solid. This material was chromatographed on a silica gel prep plate with DCM/10% ammonia/methanol (10-1) giving the product as a tan solid (0.084 g, 39%). Mp 88-91° C.
