Participants

Reaction Steps

To a suspension of 245 (18 mg, 0.062 mmol) in THF (1 mL) was added 2-phenylacetyl isothiocyanate (12 mg, 0.069 mmol). The reaction mixture was stirred for 3 hours, concentrated under reduced pressure and the residue was purified by flash chromatography, eluent hexane/EtOAc (3:2) followed by recrystallization (MeCN/water), and preparative HPLC (Aquasil C-18, gradiend: 60% MeOH to 95% MeOH in water), to afford title compound 246 (9.2 mg, 33% yield) as a white solid. 1HNMR: (CD3OD) δ (ppm): 8.35(s, 1H), 8.03 (d, J=12.4 Hz, 1H), 7.96(d, J=3.13 Hz, 1H), 7.44-7.26(m, 6H), 6.69 (d, J=3.13 Hz, 1H), 5.29 (quintuplet, J=6.65 Hz, 1H), 3.75(s, 2H), 3.60 (d, J=10.96 Hz, 3H), 1.63(d, J=6.65 Hz, 6H). MS (m/z): 464.16 (M+1).
