Reaction Steps

To a stirred solution of 3-morpholinopyrazin-2(1H)-one (317 mg, 1.75 mmol) in DMF (8 mL) at 0° C. was added NaH (60% in mineral oil, 105 mg, 2.63 mmol). After stirring for 20 min, a solution of 6-(chloromethyl)-2-(methylthio)benzo[d]thiazole (400 mg, 1.75 mmol) in DMF (2 mL) was added dropwise, and the mixture was stirred at rt for 2 h. The mixture was poured into water and extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure to give 1-((2-(methylthio)benzo[d]thiazol-6-yl)methyl)-3-morpholinopyrazin-2(1H)-one as a light yellow solid (625 mg, 95.4%). 1H NMR (300 MHz, CDCl3) δ 7.82 (d, J=8.4 Hz, 1H), 7.71 (s, 1H), 7.36 (d, J=6.6 Hz, 1H), 6.92 (d, J=4.2 Hz, 1H), 6.71 (d, J=4.2 Hz, 1H), 5.10 (s, 2H), 3.81 (s, 8H), 2.80 (s, 3H). LCMS (ESI) m/z 375 (M+H)+.
