Participants

Reaction Steps

Cyclopropylamine (10.71 mL, 155 mmol) was added to ethyl 4-amino-5-methyl-6-oxo-2-[1-(3,3,4,4,4-pentafluorobutyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine-5-carboxylate, as prepared by the procedure described in Example 158, (594 mg, 1.189 mmol) and the resultant mixture heated at 50° C. for 16 hours. The mixture was concentrated in vacuo and the residue purified by silica gel column chromatography using a hexanes/EtOAc gradient. Chiral separation using SFC on a Chiralpak AD-H column provided both enantiomers of the title compound, 1H NMR (500 MHz, DMSO-d6): δ 9.02 (1H, d, J=8.09 Hz), 8.63 (1H, d, J=4.45 Hz), 7.63 (1H, d, J=4.01 Hz), 7.38 (1H, dd, J=8.08, 4.48 Hz), 6.75 (2H, s), 4.87 (2H, t, J=6.77 Hz), 3.03-2.90 (2H, m), 2.68-2.62 (1H, m), 1.56 (3H, s), 0.63-0.54 (2H, m), 0.51-0.44 (2H, m). m/z=511.2 (M+H).
