2-{5-Chloro-2-[3-(2-hydroxy-ethyl)-8-methoxy-2,3,4,5-tetrahydro-1H-3-benzazepin-7-ylamino]-pyrimidin-4-ylamino}-N,N-dimethyl-benzenesulfonamide (80.0 mg, 0.146 mmol) was stirred in Methylene chloride (1.60 mL, 25.0 mmol) with Triethylamine (30.6 μL, 0.219 mmol) at room temperature. Propanoyl chloride (12.7 μL, 0.146 mmol) was then added quickly under nitrogen. The reaction was complete after stirring over night. The reaction mixture was washed with bicarb and extracted with XS DCM. The organic layer was dried over MgSO4 and filtered. The filtrate was chromatographed on an ISCO flash system (0-10% MeOH:DCM). The desired fractions were concentrated and the product was obtained as a foam from a small amount of DCM (35 mg, 40%). mp: 40° C. softened, 60-70 glass, MS (ESI+): 603 (M+H), 1H-NMR (CDCl3, 400 MHz) δ 9.35 (s, 1H), 8.54 (d, J=8 Hz, 1H), 8.16 (s, 1H), 8.01 (s, 1H), 7.90 (d, J=8 Hz, 1H), 7.57 (t, 1H), 7.51 (s, 1H), 7.25 (m, 1H), 6.67 (s, 1H), 4.25 (t, J=6 Hz, 2H), 3.89 (s, 3H), 2.87 (m, 2H), 2.83 (t, J=6 Hz, 2H), 2.76-2.72 (m, 12H), 2.36 (t, J=7.5 Hz, 2H), 1.17 (t, J=7.5, 3H).
