Reaction Steps

(1-(tert-Butoxycarbonyl)pyrrolidin-2-yl)zinc(II) chloride (2.75 mL, 1.02 mmol, 0.37M) was added to a 10 mL microwave vial under nitrogen, 8-Bromo-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene 27 from FIG. 4 (200 mg, 0.51 mmol), Pd(OAc)2 (12 mg) and tri-tert-butylphosphonium tetrafluoroborate (18 mg) were added. The reaction vessel was sealed and the mixture heated at 100° C. overnight. Aqueous work-up and concentration gave a crude residue which was treated with TFA in DCM (1:1 mix). After 1 h at room temperature, the solvent was removed and the residue purified by reverse phase HPLC to give 537 (10 mg, 5%). LCMS: 382.1
