Participants

Reaction Steps

To a solution of 3-(5-aminopyrazin-2-yl)cyclohex-2-enol (149 mg, 0.779 mmol) in DMF (5.5 mL) at 0° C. were added tert-butylchlorodimethylsilane (294 mg, 1.95 mmol)) and 1H-imidazole (212 mg, 3.12 mmol). The reaction mixture was stirred at room temperature overnight. After quenched with sat NaHCO3, the reaction mixture was extracted with EtOAc 3 times. The combined organic layers were dried over anhydrous sodium sulfate. Filtered and concentrated in vacuo. The crude product was purified with flash chromatography eluting with 0-100% of EtOAc/heptane to provide 238 mg of crude product which was used as it was. LCMS (m/z): 306.9 (MH+), 1.04 min.
