Reaction Steps

To a solution of 8-azetidin-3-yl-2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene, from Example 519, (0.300 g, 0.000786 mol) and cesium carbonate (0.384 g, 0.00118 mol) in N,N-dimethylformamide (7.9 mL) was added 1-chloro-3-methoxy-2-propanol (0.0844 mL, 0.786 mmol) dropwise. The reaction was heated to 50° C. overnight. Sodium iodide (0.236 g, 0.00157 mol) was added and stirring was continued at 50° C. The mixture was diluted with water and methylene chloride and extracted 3 times with methylene chloride. Purify by flash chromatography then reverse-phase HPLC to obtain 520 as a white solid (22.5 mg). MS (ESI+) 470.2
