Versuchsvorschrift

A suspension of Boc-4-aminopiperidine (613 mg, 3 mmol), 4-chloro-6-methylpyrimidine (433 mg, 3.3 mmol) and N,N-diisopropylethyl amine (771 L, 4.5 mmol) in dioxane (12 mL) was heated to 150° C. in the microwave for 30 minutes. The reaction was diluted with water and extracted twice with ethyl acetate. The combined organic layers were washed with water, dried over sodium sulfate, filtered and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel using a gradient from AcOEt to AcOEt/EtOH 9:1 as eluent. The title compound was obtained as a light yellow solid (693 mg, 79%).
