Versuchsvorschrift

A mixture of 1-((2-((3aR,7aR)-2,2-dimethylhexahydrobenzo[d]oxazol-3(2H)-yl)benzo[d]thiazol-6-yl)methyl)-1H-benzo[d]imidazol-5-ol (100 mg, 0.23 mmol) from Step 1 of this Example, 4-(2-iodoethyl)morpholine (111 mg, 0.46 mmol) from Step 2 of this Example, Cs2CO3 (250 mg, 0.69 mmol), and NMP (2 mL) was stirred at rt for 3 h. The mixture was diluted with EtOAc and washed with brine. The organic layer was separated, dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel flash chromatography, eluting with a gradient of 33% DCM in THF to 100% THF, to afford (3aR,7aR)-2,2-dimethyl-3-(6-((5-(2-morpholinoethoxy)-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]thiazol-2-yl)octahydrobenzo[d]oxazole (84 mg, 67%) as a yellow solid. 1H NMR (300 MHz, CDCl3) δ 7.90 (s, 1H), 7.58 (d, J=8.1 Hz, 1H), 7.40 (s, 1H), 7.29 (s, 1H), 7.14-7.19 (m, 2H), 6.90 (m, 1H), 5.35 (s, 2H), 4.11-4.17 (m, 2H), 3.70-3.75 (m, 4H), 3.65 (m, 1H), 3.08 (m, 1H), 2.76-2.84 (m, 3H), 2.57-2.60 (m, 4H), 2.17 (m, 1H), 1.82-1.92 (m, 2H), 1.78 (s, 3H), 1.46 (s, 3H), 1.33-1.39 (m, 4H); LCMS (ESI) m/z 548 (M+H)+.
