실험 절차

A mixture of 3-bromocyclohexane-1,2dione (158 mg, 0.827 mmol, from preparation AAE) and 1-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)thiourea (109 mg, 0.414 mmol, from step 4 of preparation F) was heated in ethanol (1.4 mL) at 80° C. for 12 h. The crude reaction was diluted with EtOAc and washed with saturated sodium bicarbonate solution. The organic layer was concentrated in vacuo. The crude product was purified using preparatory TLC (80% acetone/hexanes) to afford 2-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenylamino)-6,7-dihydrobenzo[d]thiazol-4(5H)-one (64 mg, 44% yield) as a yellow solid. LC-MS (M+H)+ 356.3. 1H NMR (400 MHz, chloroform-d) δ ppm 8.55 (s, 1 H) 7.68 (d, J=8.56 Hz, 1 H) 7.31 (d, J=2.27 Hz, 1 H) 6.96 (dd, J=8.56, 2.52 Hz, 1 H) 3.95 (s, 3H) 3.00 (t, J=6.04 Hz, 2 H) 2.59-2.68 (m, 2 H) 2.45-2.52 (m, 3H) 2.20-2.31 (m, 2H).
