Abstract:Ethyl 2-methylsulfoxide-pyrimidin-4-(3-chloro-4-methoxybenzyl)-amino-5-carboxylate(3) was synthesized by oxidation of ethyl 2-methylthiopyrimidin-4-(3-chloro-4-methoxybenzyl)-amino-5-carboxylate using 80% cumene hydroperoxide; Ethyl 2-[(R)-2-hydroxymethylpyrrolidinyl-1-]-4-(3-chloro-4-methoxybenzylamino)-5-pyrimidine carboxylate (7) was synthesized by condensation of (R)-(-)-2-(hydroxymethyl) pyrrolidine with 3; 2-[(R)-2-hydroxymethylpyrrolidinyl-1-]-4-(3-chloro-4-methoxybenzylamino)-5-pyrimidine carboxylic acid ethyl ester (8) was obtained by hydrolysis of 7 with sodium hydroxide and acidification; Under the catalysis of triethylamine in N,N-diethylacetamide, (R)-avanafil (1) was synthesized by the mixed reaction with 8, 2-aminomethylpyrimidine methanesulfonate, 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride and 1-hydroxybenzotriazole in an overall yield of 49.0%. The structure of the synthesized substance was characterized.
