참여 물질

반응 단계

Triethylamine (140 μL, 1.00 mmol) was slowly added to a solution of 4-[[2-(5-bromo-2-fluorophenyl)pteridin-4-yl]amino]nicotinic acid 16 (150 mg, 0.340 mmol), PyBOP (0.350 mg, 0.68 mmol), and 1-(β-aminopropyl)pyrrolidinone (97 mg, 0.68 mmol) in CH2Cl2 (10 mL). After 15 min at room temperature, the reaction mixture was evaporated and the residue purified by column chromatography (AcOEt/CH2Cl2, 2:1+1% triethylamine to AcOEt/CH2Cl2/MeOH, 7:2:1+1% triethylamine). The yellow powder was recrystallized from EtOH to give 58 mg of the title product 21 as yellow prisms (LCMS analysis).
