Participants

Reaction Steps

Sodium hydride (80% in oil, 63 mg, 2.1 mM) was stirred under nitrogen in N,N-dimethylformamide (2 ml), (5R)-3-(4-methylthiophenyl)-5-methanesulfonyloxymethyl-oxazolidin-2-one (630 mg, 2 mM) dissolved in N,N-dimethylformamide (10 ml) added, followed by pyrazole (140 mg, 2 mM) dissolved in N,N-dimethylformamide (2 ml). Stirring was continued for 1.5 hours at ambient temperature. After diluting with water (30 ml) and stirring for 1 hour, the precipitate was filtered to give the desired product (190 mg, mp 72–73°).
