Participants

Reaction Steps

A solution of 4-chloro-5-({[(1,1-dimethylethyl)(dimethyl)silyl]oxy}methyl)-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-2-sulfonyl chloride (0.341 g, 0.72 mmol) in acetone (4.5 mL) and THF (2.5 mL) was added to a 0° C. solution of methylamine (3.6 mL of a 2M solution in THF, 7.2 mmol) in THF (2 mL). The reaction mixture was stirred at RT for 1 h and evaporated. The residue was taken up in EtOAc and washed with brine. The organic phase was dried (Na2SO4), filtered evaporated, and purified by silica gel chromatography (0-25% EtOA/hexanes) to give the title compound (0.23 g, 68%) as a light yellow oil. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 5.85 (br. s., 1H), 5.73 (s, 2H), 4.75 (s, 2H), 3.59-3.68 (m, 2H), 2.86 (d, J=5.1 Hz, 3H), 0.93 (d, J=8.4 Hz, 2H), 0.89 (s, 9H), 0.10 (s, 6H), −0.01 (s, 9H).
