Procedure

To a solution of 8-Amino-1,4-diethyl-1,2,3,4-tetrahydro-benzo[e][1,4]diazepin-5one (22.0 g, 0.0944 mol) in dioxane (400 mL) was added borane dimethyl sulfide complex solution (2 M in THF, 118 mL, 0.236 mol) and heated at 75° C. for 4 hr. The reaction was quenched with ethanol (100 mL) and stirred at room temperature for 18 hr., then evaporated. To the residue was added hydrazine hydrate (100 mL) and heated at 95° C. for 4 hr. After evaporation, toluene (50 mL) and ethanol (50 mL) were added, distilled and the reaction evaporated. The residue was extracted with DCM, evaporated, dissolved in ether, filtered and evaporated to give 1,4-Diethyl-2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepin-8-ylamine as an oil (16.0 g, 84%). LCMS (m/e) 220 (M+1); 1H-NMR (DMSO, 400 MHz) δ 6.79-6.71 (d, 1H, J=7.83 Hz), 6.49 (br, 1H), 6.01-5.99 (d, 1H, J=7.83 Hz), 4.79 (s, 2H), 3.07-3.02 (q, 2H, J=6.82 Hz), 2.85-2.83 (t, 2H, J=8.08 Hz), 2.70-2.68 (t, 2H, J=8.09 Hz), 1.13-1.10 (t, 3H, J=7.07 Hz), 1.00-0.97 (t, 3H, J=7.32 Hz), 712d) 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. LCMS (m/e) 538 (M); 1H-NMR (DMSO, 400 MHz) δ 9.07 (s, 1H), 8.05 (s, 1H), 8.01 (s, 1H), 7.65 (d, 1H), 7.15-7.13 (d, 1H, J=8.33 Hz), 7.01 (s, 1H), 6.84-6.82 (d, 1H, J=8.08 Hz), 6.69 (s, 1H), 6.49-6.47 (d, 1H, J=8.59 Hz), 3.80 (s, 3H), 3.76 (t, 2H, J=4.05), 3.54 (s, 2H), 3.14 (t, 3H), 3.01-2.99 (q, 2H, J=7.07 Hz), 2.90-2.84 (m, 2H), 2.78-2.69 (m, 2H), 2.40-2.30 (m, 2H), 1.11-1.08 (t, 3H, J=6.57 Hz), 1.03-1.00 (t, 3H, J=7.33).
