Participants

Reaction Steps

A mixture of 2,4-dichloro-5-fluoropyrimidine (167 mg, 1.00 mmol), 4-N-Boc-aminomethyl piperidine (214 mg, 1.00 mmol) and triethylamine (0.300 mL, 2.15 mmol) in CH3CN (4 mL) was stirred at room temperature for 20 h. It was concentrated in vacuo. The residue was dissolved in nBuOH (6 mL). 2 mL of the nBuOH solution was taken, to which 6-aminoindazole (66 mg, 0.49 mmol) was added. The solution was stirred at 116° C. for 20 h. nBuOH was removed in vacuo. The residue was dissolved in TFA (2 mL). After being stirred at room temperature for 2 h, TFA was removed in vacuo. The residue was purified by HPLC to give the titled compound (40 mg). MS 342.5 (M+H); UV 205.8, 246.8, 276.8 nm.
