Procedure

2-Chloro-N-isopropylacetamide (0.124 g, 0.917 mmol) and tetra-n-butylammonium iodide (0.678 g, 0.00183 mol) were premixed in methylene chloride (3 mL). This solution was added dropwise 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 (0.350 g, 0.917 mmol) and triethylamine (0.256 mL, 0.00183 mol) in methylene chloride (7 mL). The reaction was stirred at room temperature for 24 hours. Water was added and the mixture was extracted 3 times with methylene chloride. The organic layers were combined, dried with MgSO4 and concentrated. The crude was purified by reverse-phase HPLC to obtain 527 as a white solid (51 mg).
