참여 물질

반응 단계

To a stirred solution of 4-hydroxy-3-nitrobenzoic acid (3.00 g, 0.0164 mol) in MeOH-benzene (1:4, v/v) was added dropwise 2.0 M-n-hexane solution of TMSCHN2 (8.2 mL, 0.0164 mol) at room temp. After the resulting solution was stirred for 4 hr at room temp, the mixture was evaporated off in vacuo. The oily residue was chromatographed on silica-gel with CHCl3 as eluent to afford 4.23 g (79%) methyl 4-hydroxy-3-nitrobenzoate as a pale yellow crystalline material.
