Reaction Steps

A solution of 1-[4-[5-amino-6-[5-[4-(bromomethyl)phenyl]-1,3,4-oxadiazol-2-yl]pyrazin-2-yl]-3,6-dihydro-2H-pyridin-1-yl]propan-1-one (20 mg, 0.04 mmol) and a solution of methanamine (107 μL of 2 M, 0.21 mmol) in THF was heated at 65° C. for 6 h. The reaction mixture was allowed to cool to room temperature and the solvents were evaporated under reduced pressure. The crude material obtained was dissolved in DMF (1 mL), filtered and purified by mass directed reverse phase LC/MS (1-99% ACN/H2O (5 mM HCl)) to yield 1-[4-[5-amino-6-[5-[4-(methylaminomethyl)phenyl]-1,3,4-oxadiazol-2-yl]pyrazin-2-yl]-3,6-dihydro-2H-pyridin-1-yl]propan-1-one (9 mg, 45%). 1H NMR (400 MHz, DMSO-d6) δ 9.28 (s, 2H), 8.58 (s, 1H), 8.18 (d, J=7.7 Hz, 2H), 7.80 (d, J=8.0 Hz, 2H), 7.63 (s, 2H), 6.66 (s, 1H), 4.30-4.13 (m, 4H), 3.70 (dt, J=16.2, 5.4 Hz, 2H), 2.71 (s, 1H), 2.59 (t, J=5.2 Hz, 4H), 2.41 (dt, J=21.8, 7.3 Hz, 2H), 1.03 (q, J=7.0 Hz, 3H). LC/MS m/z 420.5 [M+H]+.
