| titleOfInvention | Avanafil preparation method |
| abstract | Disclosed is a method for preparing avanafil (I) by using cytosine as the starting material. The preparation steps comprise: using cytosine as the raw material, and enabling the cytosine to react with side chain 3-chlorine-4-methoxybenzyl halogen, N-(2-methylpyrimidine) methanamide and S-hydroxymethyl pyrrolidine, to prepare the target product avanafil (I). For the preparation method, the raw material is easily obtained, and the process is simple, economical, and environmentally friendly, so the method meets the requirement of industrial boost. |
