Reaction Steps
5-Chloro-N*2*-(1,4-diethyl-2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepin-8-yl)-N*4*-(2-methoxy-4-morpholin-4-yl-phenyl)-pyrimidin-2,4-diamine was prepared from 1,4-Diethyl-2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepin-8-ylamine (0.068 g, 0.00023 mol) and (2,5-Dichloro-pyrimidin-4-yl)-(2-methoxy-4-morpholin-4-yl-phenyl)-amine (0.081 g, 0.00023 mol), camphorsulfonic acid (0.0187 g, 0.0008 mol) and methoxyethanol (10 mL). The mixture was heated at 95° C. for 18 hr. The reaction was evaporated and the residue treated with a 10% sodium carbonate solution and DCM, separated, washed, dried and evaporated to give a solid. This material was chromatographed on a silica gel prep plate with THF/methanol (10-1) giving the product as a tan solid (0.053 g, 43%). Mp 165-166° C.
