Reaction Steps

A mixture of 6-bromo-4-(((3aS,4R,5R,6aS)-4-methyl-2-(methylsulfonyl)octahydrocyclopenta[c]pyrrol-5-yl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide from Step 3 of Example 59 (70 mg, 0.153 mmol) and copper(I) cyanide (27.5 mg, 0.307 mmol) in 1-methyl-2-pyrrolidinone (1 mL) was heated to 220° C. under microwave for 2 h. The resulting mixture was diluted with ethyl acetate (80 mL), washed with saturated NH4Cl, water, brine, dried (MgSO4) and concentrated. The residue was purified by silica gel chromatography, eluting with 60-100% ethyl acetate in hexanes, to give 6-cyano-4-(((3aS,4R,5R,6aS)-4-methyl-2-(methylsulfonyl)octahydrocyclopenta[c]pyrrol-5-yl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide (35 mg, 56% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.43 (d, J=1.8 Hz, 1H), 8.37 (s, 1H), 7.61 (d, J=1.5 Hz, 1H), 4.24-4.01 (m, 1H), 3.26-3.11 (m, 2H), 3.05 (m, 1H), 2.93 (s, 3H), 2.93-2.83 (m, 1H), 2.61-2.54 (m, 1H), 2.36-2.17 (m, 1H), 1.93-1.82 (m, 1H), 1.70-1.55 (m, 1H), 1.36-1.25 (m, 1H), 1.10-1.02 (m, 3H).
