1-(2-aminopropyl)pyrrolidin-2-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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). the reaction mixture was evaporated 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
