Versuchsvorschrift

A mixture of methyl[2-(4-aminobenzyl)-4,6-dichloropyrimidin-5-yl]acetate (0.073 g, 0.23 mmol), 2-naphthoic acid (0.048 g, 0.028 mmol), and WSCI (0.049 g, 0.026 mmol) in anhydrous THF (3 mL) was stirred at room temperature under Ar atmosphere for 10 hours. EtOAc (80 mL) was then introduced and the organic phase was washed sequentially with saturated NaHCO3, water, and brine, dried over anhydrous MgSO4, filtered, and concentrated in vacuo. The crude product thus obtained as a light orange oil was triturated with diisopropyl ether and the separated solids was collected by suction to give methyl {4,6-dichloro-2-[4-(2-naphthoylamino)benzyl]pyrimidin-5-yl}acetate (0.090 g, 78% yield) as a white powder.
