실험 절차

tert-Butyl 4-fluoro-2-(5-nitro-4-thiocyanatopyrimidin-2-ylamino)phenylcarbamate (2.0 g) was added to a solution of (R)-8-fluorochroman-4-amine hydrochloride (1.1 gram) and N,N-diisopropylethylamine (2.2 mL) in THF (anhydrous, 50 mL). The mixture was stirred for 6 hr at room temperature then partitioned between water and EtOAc and separated. The aq. layer was washed with additional EtOAc and the combined organics were dried over Na2SO4 and concentrated in vacuo to give the title product in 94% yield. MH+=515, 459 (-tBu).
