Product Description

The Vilazodone hydrochloride intermediate 5-(1-Piperazinyl)benzofuran-2-carboxamide CAS Number is 183288-46-2. Regarding his synthesis method, more methods reported in the literature is using 5-bromo salicylaldehyde as raw material and ethyl bromoacetate to prepare ethyl 5-bromobenzofuran-2-carboxylate, and then present in sodium methoxide and formamide reaction to obtain 5-bromobenzofuran-2-carboxamide, and finally reacted with piperazine under the catalysis of transition metal catalyst Pd(OAc)2/P(t-Bu)3 to obtain 5-(1-Piperazinyl)benzofuran-2-carboxamide CAS Number 183288-46-2. The biggest disadvantage of this method is that the catalyst used in the reaction process is expensive and difficult to purchase, and has high risk and is not suitable for industrial production.
After exploration, an improved method has been proposed. The specific process is as follows: Add 50gram 5-aminobenzofuran-2-carboxylic acid ethyl ester,50gram  N,N-bis(2-chloroethyl)amine and 500 ml of diethylene glycol monomethyl ether into a 1L reaction flask. warmed to 130℃, react for 12 hours, suction filtration, filter cake was added to 200 ml of water, adjusted to pH 9-10 with saturated sodium carbonate solution, Extract with ethyl acetate (500 ml × 2 ), dried with anhydrous sodium sulfate, and the solvent was evaporated to dry to get light yellow crystals ,That is the target compound 5-(1-Piperazinyl)benzofuran-2-carboxamide CAS Number is 183288-46-2.
