Dimethylamine → HCID 53665129, compound

Participants

Reaction Steps

A mixture of 12.90 g (0.025 mole) of 1-[2-(o-chlorobenzoyl)-4-chlorophenyl]-5-(iodomethyl)-1H-1,2,4-triazole-3-carboxylic acid methyl ester [see Example 13 (b)] and 11 ml of 33% ethanolic dimethylamine solution in 250 ml of methanol is stirred for 7 hours at room temperature. The reaction solution is thereupon concentrated in vacuo; water is added to the residue and the whole is extracted twice with methylene chloride. The organic phase is washed twice with water and once with saturated sodium chloride solution; it is dried over sodium sulphate and concentrated in vacuo to dryness. The amorphous residue is dissolved in 130 ml of ether; the solution is allowed to stand and the reaction product then crystallises out. It is filtered off with suction and washed with ether. After drying there is obtained 1-[2-(o-chlorobenzoyl)-4-chlorophenyl)-5-[(dimethylamino)-methyl]-1H-1,2,4-triazole-3-carboxylic acid methyl ester, m.p. 131°-134°.
