HCID 442425624-(6,7-Dihydropyrido[3,2-b]thieno[2,3-d]oxepin-9-yl)-(5-(2-chlorophenyl))-thiazol-2-amine

Procedure

6,7-Dihydropyrido[3,2-b]thieno[2,3-d]oxepin-9-yl-(2-chlorophenyl)-2-bromoethanone from Example 37 (100.0 mg, 0.230 mmol) and thiourea (20.14 mg, 0.264 mmol) were heated in ethanol (5 mL, 80 mmol) for 1 hour. The solvent was evaporated to half of the volume, whereupon the product crystallized upon standing. The product 165 was collected by filtration and washed with cold ethanol (yield 43 mg, 45%). 1H NMR (400 MHz, DMSO) δ 8.15 (d, J=3.2, 1H), 7.66 (d, J=8.2, 1H), 7.54 (t, J=7.6, 2H), 7.47 (t, J=7.4, 1H), 7.36 (d, J=8.1, 1H), 7.16 (dd, J=4.5, 8.1, 1H), 6.73 (s, 1H), 5.80-4.90 (m, 2H), 4.24 (t, J=4.7, 2H), 3.04 (t, J=4.7, 2H). MS (ESI+) 412.1
