Participants

Reaction Steps

In a 500-mL round-bottom flask, (S)-2-(4-methyl-1H-imidazol-1-yl)propan-1-ol (12.0 g) and TEA (12 mL) were dissolved in DCM at room temperature. To this solution, TBSCl (21.3 g, 0.141 mol) was added, and the resulting mixture was stirred at room temperature overnight. The mixture was washed with H2O, the organic phase was separated, and the aqueous was extracted with DCM. The combined organic layers were washed with brine (50 mL), dried over Na2SO4, filtered, and concentrated in vacuo. The residue was purified on a silica gel column eluted with 1/30˜1/9 MeOH/DCM, affording a sample (1.20 g), which was further purified by prep-HPLC, to afford the title compound (0.557 g). 1H NMR (CDCl3): δ 7.41 (d, 1H), 6.67-6.65 (m, 1H), 4.16-4.10 (m, 1H), 3.73-3.62 (m, 2H), 2.20 (d, 3H), 1.44 (d, 3H), 0.86 (s, 9H), −0.04 (s, 6H); LCMS: 255 (M+H)+.
