Heptanoic Acid → HCID 23354796, compound

Participants

Reaction Steps

In a 50 ml-round-bottomed flask, 0.60 g (1.89 mM) of 2-decyl-5-(4-hydroxyphenyl)thiazole, 0.28 ml (1.97 mM) of heptanoic acid and 15 ml of dichloromethane were placed and mixed. To the solution, 0.39 g (1.89 mM) of N,N'-dicyclohexylcarbodiimide and 0.03 g of 4-pyrrolidinopyridine were successively added under stirring at room temperature, followed by further stirring for 2 hours at room temperature. After stirring, the mixture was left standing overnight at room temperature to precipitate N,N'-dicyclohexylurea. The resultant N,N'-dicyclohexylurea was filtered off and the solvent of the filtrate was distilled-off under reduced pressure. The residue was purified by silica gel column chromatography (eluent: toluene) and recrystallized from acetone to obtain 0.62 g of 2-decyl-5-(4-heptanoyloxyphenyl)thiazole (Yield: 76.4%). ##STR92##
