Reaction Steps

A mixture of 4-fluorobenzonitrile (121 mg, 1 mmol), compound 37-7 (308 mg, 1 mmol), and Cs2CO3 (326 mg, 1 mmol) in DMF (2 mL) was heated at 160° C. in a microwave (Biotage initiator) for 20 minutes. The mixture was extracted with EtOAc (2×20 mL) and dried over MgSO4. After the removal of ethyl acetate via rotary evaporator the residue was subjected to flash chromatography using DCM/MeOH as the eluent to give S)-6-((1-amino-1-oxopropan-2-yl)amino)-2-(4-(4-cyanophenoxy)piperidin-1-yl)pyrimidine-4-carboxamide (Cpd. No. 100) as a white solid (150 mg). 1H NMR (CD3OD) δ 7.55-7.65 (m, 2H), 7.12 (m, 2H), 6.40 (s, 1H), 4.80 (m, 1H), 4.30 (m, 1H), 3.95 (m, 2H), 3.68 (m, 2H), 1.98 (m, 2H), 1.75 (m, 2H), 1.40 (d, 3H). LC/MS: m/z=410 [M+H]+.
