Definition

ChEBI: An anilide resulting from the formal condensation of the aryl amino group of N-phenyl-1-[2-(2-thienyl)ethyl]piperidin-4-amine with propanoic acid.

Check Digit Verification of cas no

The CAS Registry Mumber 1165-22-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,6 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1165-22:
(6*1)+(5*1)+(4*6)+(3*5)+(2*2)+(1*2)=56
56 % 10 = 6
So 1165-22-6 is a valid CAS Registry Number.

Improved method for the total synthesis of thiofentanyl

Hosseini, S. J.,Moosavi, S. M.,Parsa, H.,Taghizadeh, M. J.

, (2020)

Thiofentanyl is a potent analgesic and anesthetic drug that belongs to the microreceptor agonist group and is mainly used in animal's anesthesia. We present an optimized synthesis route for synthesis of thiofentanyl using nanocatalysts such as MCM-41-SO3H and SBA-15-Ph-PrSO3H as green, heterogeneous and recyclable catalysts according to the strategy. The intermediate 2-(thiophen-2-yl) ethyl methanesulfonate (1) easily obtained after conversion of the alcohol functional group into the mesylate leaving group using methanesulfonyl chloride (97% yield). The alkylation of commercially available 4-piperidone monohydrate hydrochloride with 2-(thiophen-2-yl) ethyl methanesulfonate in the presence of phase transfer catalyst was then carried out giving N-[2-(2-thienyl) ethyl]-4-piperidone (2) with 90% yield. N-[2-(2-thienyl)ethyl]-4-piperidone was then reacted with aniline in the presence of MCM-41-SO3H catalyst giving the imine derivative which reduced with sodium triacetoxyborohydride to N-phenyl-1-(2-(thiophen-2-yl)ethyl) piperidine-4-amine (ANTP) (4) with 80% yield. ANTP was finally acylated using propionyl chloride to achieve thiofentanyl (5) with 90% yield. High yields, mild reaction conditions, decreased reaction times, and convenient workup were the advantages of this method compared to the previous work.
