Hydrochloric Acid → HCID 12056523, compound

Participants

Reaction Steps

6.29 g (21.3 mmol) of 5-hydroxymethyl-4-(2-methyl-5-phenylbenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one, 3.53 g (25.6 mmol) of potassium carbonate and 3.63 g (25.6 mmol) of methyl iodide were stirred for 4 hours at 60° C. in 38 mol of anhydrous N,N-dimethylformamide. To the reaction solution was added 200 ml of a 5 wt % hydrochloric acid aqueous solution, and this was extracted with ethyl acetate. The organic layer was washed with water, 5 wt % sodium bicarbonate solution, then, saturated saline, dried over anhydrous magnesium sulfate, then, concentrated. The residuie was subjected to silica gel column chromatography (eluant: hexane/ethyl acetate=1/1 (v/v), then, ethyl acetate), to obtain 6.52 g (21.2 mmol) of 5-hydroxymethyl-2-methyl-4-(2-methyl-5-phenylbenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one.
