HCID 582038588-(1-Azetidin-3-yl-1H-pyrazol-4-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

Procedure

Similarly to as described in General Procedure C, 8-Bromo-2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene was reacted with tert-butyl 3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)azetidine-1-carboxylate. Removal of the tertbutoxycarbonyl protecting group was accomplished with trifluoroacetic acid in dichloromethane. Purification of the crude reaction mixture by reverse phase HPLC gave 406. LCMS: 448.2
