Phenyl chloroformate (0.03 mL, 0.24 mmol) was added slowly to a solution of 3-Cyclopropyl-1′-methyl-1′H-[1,4′]bipyrazolyl-5-ylamine (Preparation 297, 40 mg, 0.19 mmol) and pyridine (0.03 mL) in THF (2 mL) at 00° C. and the mixture was stirred at room temperature for 4 hours. A solution of (5-Amino-pyridin-3-yl)-(7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanone (Preparation 95) (55.4 mg, 0.19 mmol) in DMF (1 mL) and was then added and the reaction mixture heated at 100° C. for 16 hours. The mixture was cooled and diluted with ethyl acetate (15 mL), and washed with aqueous saturated NaHCO3 solution (2×10 mL), water (10 mL), brine (10 mL), dried over sodium sulphate and evaporated to dryness in vacuo. The crude material was purified over preparative TLC plate (eluting with 5% methanol in DCM) to afford the title compound as off white solid in 15% yield, 15 mg. 1H NMR (400 MHz, DMSO-d6) δ: 0.64-0.65 (m, 2H), 0.85-0.88 (m, 2H), 1.56 (d, 6H), 1.82-1.85 (m, 1H), 3.89 (s, 3H), 5.09-5.12 (m, 1H), 6.10 (s, 1H), 7.66 (s, 1H), 8.05 (s, 1H), 8.36 (s, 1H), 8.52 (s, 1H), 8.61 (br s, 1H), 8.65 (s, 1H), 8.78 (s, 1H), 8.99 (s, 1H), 9.45 (s, 2H); LCMS (system 10): Rt=2.75 min; m/z 511 [M+H]+.
