Reaction Steps

Crude 4-{[trans-3-(methylamino)cyclobutyl]oxy}-N-(1-methyl-1H-pyrazol-4-yl)-5-(pyridin-3-yl)-7H-pyrrolo[2,3-d]pyrimidin-2-amine (0.4 mmol) was partitioned between water (8 mL) and ethyl acetate (15 mL). Acryloyl chloride (36 μL, 0.44 mmol) was added and the mixture stirred at ambient temperature for 1 hr. The organic layer was separated, dried over Na2SO4 and evaporated to give a residue, which was purified by SFC (Zymor Spher Diol Monol, 150×21.2 mm, 5 μm column at 35° C. eluting with a 20%-50% EtOH gradient at 5%/min in CO2 at 140 bar with a flow rate of 60 mL/min) to give the title compound (7.4 mg, 4% yield). 1H NMR (700 MHz, DMSO-17 mm) δ ppm 11.64 (br. s., 1H) 8.87-9.00 (m, 2H) 8.43 (d, J=3.96 Hz, 1H) 8.12 (d, J=7.26 Hz, 1H) 7.87 (br. s., 1H) 7.52 (s, 1H) 7.42 (br. s., 1H) 7.33 (s, 1H) 6.59-6.80 (m, 1H) 5.95-6.15 (m, 1H) 5.65 (br. s., 2H) 5.47 (br. s., 1H) 3.74-3.88 (m, 3H) 3.07 (br. s., 1H) 2.91-3.00 (m, 1H) 2.72 (br. s., 2H) 2.29-2.46 (m, 2H). m/z (APCI+) for C23H24N8O2 445.2 (M+H)+.
