Procedure

A mixture of methyl {4,6-dichloro-2-[4-(2-naphthoylamino)benzyl]pyrimidin-5-yl}acetate (0.100 g, 0.21 mmol), pyrrolidine (0.019 mL, 0.23 mmol), and N,N-diisopropylethylamine (0.109 mL, 0.62 mmol) in anhydrous DMF (2 mL) was stirred at 80° C. for 5 hours. After cooling to room temperature, the solvent was evaporated and the remaining residue dissolved in EtOAc. This organic solution was sequentially washed with 1N HCl, water, and brine, dried over anhydrous MgSO4, filtered, and concentrated in vacuo. Purification by preparative TLC then afforded methyl {4-chloro-2-[4-(2-naphthoylamino)benzyl]-6-pyrrolidin-1-ylpyrimidin-5-yl}-acetate (0.100 g, 95% yield) as a white powder.
