Reaction Steps

(S)-(1-(7-(3,5-Difluorophenyl)-3-iodo-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)pyrrolidin-2-yl)methanol (40 mg), 3,4-methylenedioxyphenylboronic acid (23 mg) and tetrakis(triphenylphosphine)palladium (10 mg) are added to toluene (5 mL), ethanol (3 mL) and 1 N NaHCO3 aqueous solution (1.5 mL) and stirred at 85° C. for 4 hours under argon atmosphere. After cooling to room temperature, the reaction solvent is removed by distillation under reduced pressure. The remainder is extracted with ethyl acetate and water. The organic layer is washed with brine and dehydrated with anhydrous MgSO4. The dehydrated organic layer is concentrated by distillation under reduced pressure and purified by column chromatography to yield the target compound (36 mg).
