실험 절차

To a solution of N-(3-(2-oxa-6-azaspiro[3.3]heptan-6-yl)phenyl)-5-chlorothiazolo[5,4-d]pyrimidin-7-amine (160 mg, 0.5 mmol) and methyl 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (145 mg, 0.55 mmol) in 9 mL of 1,4-dioxane and 1 mL of water was added Na2CO3 (159 mg, 1.5 mmol) followed by Pd(PPh3)4 (58 mg) under nitrogen with stirring. The mixture was refluxed for 15 hours under nitrogen. After cooled, the solvent was evaporated by rotary evaporation. The residue was poured into water and extracted with EtOAc (3×10 mL). The organic layer was washed with brine and dried over Na2SO4. After filtration and concentration, the residue was purified by column chromatography on silica gel eluting with (petroleum ether EtOAc=1:1) to give methyl 3-(7-(3-(2-oxa-6-azaspiro[3.3]heptan-6-yl)phenylamino)thiazolo[5,4-d]pyrimidin-5-yl)benzoate (70 mg, 30%). LC-MS: 460 [M+H]+, tR=1.74 min.
