Morpholine → HCID 53701460, compound

Participants

Reaction Steps

A mixture of 38.7 g (0.075 mole) of 1-[2-(o-chlorobenzoyl)-4-chlorophenyl]-5-(iodomethyl)-1H-1,2,4-triazole-3-carboxylic acid methyl ester and 13.1 g (0.150 mole) of morpholine in 750 ml of methanol is stirred for 8 hours at 40°. The reaction mixture is then concentrated in vacuo; water is added to the residue and extraction is performed twice with methylene chloride. The organic phase is washed three times with water and twice with saturated sodium chloride solution; it is dried over sodium sulphate and concentrated in vacuo. The residue is triturated with ether, whereupon the reaction product is obtained in crystalline form. After filtration with suction and drying in vacuum, there is obtained 1-[2-(o-chlorobenzoyl)-4-chlorophenyl]-5-(morpholinomethyl)-1H-1,2,4-triazole-3-carboxylic acid methyl ester, m.p. 141°-143°.
