실험 절차

To a solution of isophthalaldehyde (40 g, 0.3 mol.) in chloroform (400 mL) and methyl 3-mercaptopropanoate (68 mL, 0.6 mol.) was added dropwise trimethylsilyl chloride (48 mL, 0.38 mol.) over 30 min. The reaction mixture was stirred at R.T. for 2 hours. The reaction was quenched with 25% aq. NH4OAc, extracted with ethyl acetate dried and evaporated. Flash chromatography of the residue afforded 50 gl of the title compound.
