Participants

Reaction Steps

To 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (30 mg, 0.072 mmol) was added 3-({[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methyl}amino)propanenitrile (24.8 mg, 0.086 mmol). To this mixture was added dioxane (0.75 mL), followed by a solution of potassium carbonate (60 mg, 0.434 mmol) in water (0.25 mL) and SK-0002-A (4.4 mg, 0.007 mmol). The vials were capped and reacted in a CEM microwave at 150° C. for 30 min. The reaction was loaded onto a 2 g SCX SPE cartridge primed with 3 mL of methanol. The cartridge was then sequentially eluted with water (3 mL), methanol (9 mL), and 2M NH3 in MeOH (6 mL). The NH3 in MeOH fractions were dried under a stream of N2 at 40° C. The crude product was purified on the Agilent MDAP with UV (230 nm) and MS detection. The desired fractions were passed thru a 5 g CHQAX cartridge primed with 4 mL of methanol and 4 mL of water. The solvents were evaporated under a stream of N2 at 65° C. to give 6.2 mg of the title compound (17.4%).
