Reaction Steps

A mixture of (R)-methyl 2-(5-bromo-4-(trifluoromethyl)pyrimidin-2-yl)-1-isopropyl-7-(methylsulfonyl)-1,2,3,4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyrazine-8-carboxylate (7 mg, 0.012 mmol), Pd(PPh3)4 (1 mg, cat. Amount), 2M aq. K2CO3 solution (100 μL, excess), and dry 1,4-Dioxane (700 μL) was degassed and refilled with nitrogen gas for 3 times. A solution of 2,4,6-trimethyl-1,3,5,2,4,6-trioxatriborinane (5 mg, excess) in dry 1,4-Dioxane (100 μL) was added. The mixture was heated in a microwave oven for 30 minutes at 120° C. After concentration, the residue was filtered and purified by Gilson to afford 3.5 mg (R)-methyl 1-isopropyl-2-(5-methyl-4-(trifluoromethyl)pyrimidin-2-yl)-7-(methylsulfonyl)-1,2,3,4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyrazine-8-carboxylate (56% yield). LC-MS: m/z 512.3 [M+H]+.
