Triethylamine → HCID 15583177, compound

Participants

Reaction Steps

A mixture of 159 g of methyl anthranilate (1.053 mole), 5 ml of triethylamine and 134 g of n-propylisocyanate (1.58 mole) in 700 ml of petroleum ether (60°-80° C.) was refluxed for seventeen hours until TLC (CH2Cl2, silica) indicated that no methyl antranilate remained. The mixture was cooled and the precipitate was filtered off, washed with a little cold petroleum ether and dried under vacuum at room temperature to obtain 236 g (95% yield) of methyl N-(N'-n-propylcarbamoyl)-anthranilate melting at 101.5°-102.5° C.
