실험 절차

A mixture of (4-fluoromethylpyrimidin-2-yl)carbamic acid tert-butyl ester (140 mg, 0.62 mmol) and TFA (2 mL) in DCM (2 mL) was stirred at room temperature for 1 hour then concentrated under reduced pressure. The residue was purified by SCX-2 chromatography (washing with methanol and eluting with 2M ammonia in methanol) to afford the title compound as a yellow solid (78 mg, quant. yield). 1H NMR (400 MHz, CDCl3): δ 8.34 (d, J=5.1 Hz, 1H), 6.79-6.78 (m, 1H), 5.33-5.30 (m, 1H), 5.21-5.19 (m, 1H), 5.13 (s, 2H).
