Reaction Steps

A suspension of 7-(4-bromo-2,6-dimethylphenyl)-4-chloro-2,5-dimethyl-5,7-dihydropyrrolo[2,3-d]pyrimidin-6-one (7.5 g), ethyl isonipecotate (4.7 g), N,N-diisopropylethylamine (3.8 g) in ethanol (35 mL) was heated at reflux for 12 hours. The reaction mixture was stirred at room temperature to afford a solid. The solid was collected by filtration and washed with cold ethanol to give 1-[7-(4-bromo-2,6-dimethylphenyl)-2,5-dimethyl-6-oxo-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl]piperidine-4-carboxylic acid ethyl ester (7.7 g).
