실험 절차

A solution of 1-cyclopropyl-3-[2-(methylsulfanyl)pyrimidin-4-yl]propan-2-one (2) (216.3 mg, 0.973 mmol) in DMF-DMA (1303 μl, 9.73 mmol) was stirred at 80° C. for 2 hours. The reaction was partitioned between water and EtOAc. The organic layer was separated, and the aqueous layer was back-extracted. The organic extracts were combined, washed with brine, dried over sodium sulfate, then concentrated in vacuo. The crude product was purified by Biotage™ silica gel chromatography [25 g ISOLUTE column, 100% DCM to 10% MeOH/DCM] to obtain the desired product as a orange-yellow solid (186.8 mg, 69.2% yield). MS (ES+): m/z=278.2/279.2 (100/50) [MH+]. HPLC: tR=0.99 minute over 3 minutes. Purity: 100% [HPLC (LC/MS) at 220 nm].
