Procedure

(8-Bromo-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl)-((R)-2-hydroxymethyl-pyrrolidin-1-yl)-methanone (0.297 g, 0.726 mmol), 4,4,5,5-Tetramethyl-2-(1H-pyrazol-4-yl)-1,3,2-dioxaborolane (0.211 g, 1.09 mmol), 2 M Sodium bicarbonate in water (1 mL, 2.0 mmol) and acetonitrile (2 mL, 40 mmol) were combined in a microwave vial and thoroughly purged with nitrogen. Added Tetrakis(triphenylphosphine)palladium(0) (0.0838 g, 0.0726 mmol) and heated on the Emrys microwave at 150° C. for 10 minutes. Cooled to room temperature, diluted with ethyl acetate, washed with brine and concentrated the organic layer in vacuo. Purified by HPLC to give 101 (48 mg, 17% yield, M+1 397.1)
