(5R)-5-(bromomethyl)pyrrolidin-2-one

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

Procedure: (R)-5-Bromomethylpyrrolidin-2-one (15 mg) was added to a suspension of 1-(4-cyclopentyloxyphenyl)-3-[4-(3-methyaminopyrrolidin-1-yl)phenyl]urea (30 mg) and potassium carbonate (20 mg) in DMF (3 ml). After 2 hours, the reaction mixture was filtered and concentrated, and the residue was purified by preparative HPLC. This resulted in the product with the molecular weight of 491.64 (C28H37N5O3); MS (ESI): 492 (M+H+) as hydrotrifluoroacetate. the reaction mixture was filtered concentrated the residue was purified by preparative HPLC This resulted in the product with the molecular weight of 491.64 (C28H37N5O3)
