실험 절차
To a solution of (Z)-1-cyclopropyl-4-(dimethylamino)-3-(2-(methylthio)pyrimidin-4-yl)but-3-en-2-one (3) in DMF (4 mL), 1-(2-hydroxy-2-methylpropyl)guanidine (529 mg, 3.15 mmol) and potassium carbonate (872 mg, 6.31 mmol) were added, and the reaction mixture was stirred at 120° C. for 2 h. The reaction mixture was purified by a reverse-phase Gilson HPLC [30-90% organic phase over 15 min] followed by a Biotage silica gel chromatography [10 g SNAP column, 100% DCM to 12% MeOH/DCM] to obtain the desired product as a glassy solid (90 mg, 21% yield). MS (ES+): m/z=392.2/393.2/394.3 (100/40/10) [MH+]. HPLC: tR=1.12 min over 3 min. Purity: 100% [HPLC (LC/MS) at 220 nm].
