◆ solutions to specific process steps: actively communicate and solve the reaction defects that are difficult to be solved in the process.
◆ solutions to API quality problems: improve the quality of intermediates or API through technological means.
◆ cost solution: reduce reaction steps, intermediate or API production costs, and improve product competitiveness.
◆ patent circumvention solution: form new innovation points with minimum cost to ensure the rationality of production process.
