Sodium hydride → [4-(4-[1,2,3]Triazol-1-yl-but-1-enyl)-phenyl]-{2-[2-(4-trifluoromethane-sulfinyl-phenyl)-vinyl]-oxazol-4-ylmethyl}-carbamic acid tert-butyl ester

Participants

Reaction Steps

A solution of [4-(4-[1,2,3]triazol-1-yl-but-1-enyl)-phenyl]-carbamic acid tert-butyl ester (0.157 g, 0.5 mmol) in N,N-dimethyl formamide (4 ml) was treated with sodium hydride (0.014 g, 0.5 mmol) and stirred for 30 min at room temperature. After addition of 4-chloromethyl-2-[2-(4-trifluoromethanesulfinyl-phenyl)-vinyl]-oxazole (0.168 g, 0.5 mmol) and stirring for 12 h the reaction was quenched by the addition of a sat. NH4Cl solution (8 ml). Extraction with ethyl acetate (3×10 ml), washing with water, drying over sodium sulfate and concentration in vacuo yields crude [4-(4-[1,2,3]triazol-1-yl-but-1-enyl)-phenyl]-{2-[2-(4-trifluoromethane-sulfinyl-phenyl)-vinyl]-oxazol-4-ylmethyl}-carbamic acid tert-butyl ester (0.28 g) which was used in the next step without any further purification.
