Reaction Steps

A solution of N-(5-(5-(4-(difluoromethoxy)phenyl)pyrimidin-2-ylamino)-2-methylphenyl)-4,7-diazaspiro[2.5]octane-7-carboxamide D8 (0.05 mmol), HCHO (0.15 mmol, 30% aqueous) and anhydrous Na2SO4 (1.5 mmol) in DCM (2 mL) is stirred at rt for 30 min. Then NaHB(OAc)3 (0.3 mmol) is added and the resulting mixture is stirred for 12 h. Purification by prep-HPLC (ACN gradient 10-70%) affords N-(5-(5-(4-(difluoromethoxy)phenyl)pyrimidin-2-ylamino)-2-methylphenyl)-4-methyl-4,7-diazaspiro[2.5]octane-7-carboxamide D9. 1H NMR (400 MHz, d6-DMSO) δ 9.67 (s, 1H), 8.79 (s, 2H), 7.98 (s, 1H), 7.76 (d, J=8.4 Hz, 2H), 7.60 (s, 1H), 7.48 (d, J=8.4 Hz, 1H), 7.27 (d, J=8.4 Hz, 2H), 7.26 (t, J=76.0 Hz, 1H), 7.08 (d, J=8.4 Hz, 1H), 2.78 (m, 2H), 2.51 (m, 4H), 2.31 (s, 3H), 2.10 (s, 3H), 0.62 (m, 2H), 0.50 (m, 2H). MS (m/z) (M+1)+: 537.1.
