Trimethylsilyldiazomethane → HCID 22644909, compound

Participants

Reaction Steps

To a solution of 2-({[4-(2-butynyloxy)phenyl]sulfonyl}amino)-4-[(2-hydroxyethyl)sulfanyl}butanoic acid (20.8 g) in ether and methanol was dropwise added trimethylsilyldiazomethane (25 mL, 2.0 M in hexanes). The reaction mixture was concentrated in vacuo and the resulting oil was chromatographed on silica gel eluting with hexane/ethyl acetate to give methyl 2-({[4-(2-butynyloxy)phenyl]sulfonyl}amino)-4-[(2-hydroxyethyl)sulfanyl]butanoate as a light yellow oil (6.68 g).
