Reaction Steps

A mixture of 1-((2-(methylsulfinyl)benzo[d]thiazol-6-yl)methyl)-3-morpholino pyrazin-2(1H)-one (250 mg, 0.64 mmol), (1R,2R)-2-aminocyclohexanol (221 mg, 1.92 mmol) and DIEA (248 mg, 1.92 mmol) in DMA (6.6 mL) was stirred at 130° C. for 16 h. The reaction mixture was cooled to rt and poured into water (30 mL). The mixture extracted with ethyl acetate (3×100 mL) and the combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography eluting with 1:5 petroleum ether/ethyl acetate to give 1-((2-(((1R,2R)-2-hydroxycyclohexyl)amino)benzo[d]thiazol-6-yl)methyl)-3-morpholinopyrazin-2(1H)-one as a light yellow solid (120 mg, 26.5%). 1H NMR (300 MHz, DMSO-d6) δ 7.96 (d, J=7.2 Hz, 1H), 7.63 (s, 1H), 7.30 (d, J=8.4 Hz, 1H), 7.18-7.22 (m, 2H), 6.90 (d, J=4.8 Hz, 1H), 5.01 (s, 2H), 4.72 (d, J=5.1 Hz, 1H), 3.65 (s, 8H), 3.55-3.52 (m, 1H), 3.36-3.31 (m, 1H), 2.07-2.02 (m, 1H), 1.90-1.86 (m, 1H), 1.63-1.62 (m, 2H), 1.30-1.22 (m, 4H). LCMS (ESI) m/z 442 (M+H)+.
