A solution of methyl 5-(imino(methylthio)methyl)-2-isopropyl-4-methylbenzoate (compound 196.5, 800 mg, 3.01 mmol, 1.00 equiv) and 2-methoxyacetohydrazide (compound 190.6, 1.90 g, 18.3 mmol, 5.00 equiv) in acetic acid (30 mL) was stirred for 2 h at 80° C. in an oil bath, then concentrated in vacuo. The residue was purified using silica gel column chromatography with ethyl acetate/petroleum ether (1:50-1:2) as eluent to yield 250 mg (27%) of methyl 2-isopropyl-5-(5-(methoxymethyl)-4H-1,2,4-triazol-3-yl)-4-methylbenzoate as a clear oil.
