Procedure

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 (0.811 g, 0.000786 mol) in ethanol (4.0 mL, 0.068 mol) was added methyl vinyl sulfone (0.0703 mL, 0.000786 mol) via syringe. The reaction was stirred at room temperature overnight. The mixture was partitioned between saturated sodium bicarbonate and methylene chloride and extracted 3 times with methylene chloride. The organic phases were combined, dried with MgSO4, and concentrated. The crude was purified by reverse-phase HPLC to give 491 (213.4 mg) as a colorless solid.
