A flow conversion system for a manufacturing process includes a flow decomposition module decomposing a process in a target process flow into lower processes based on a process decomposition table to create an intermediate lower process flow; a compatible flow generation module replacing the lower processes with a lower compatible process based on a lower process compatibility table to create an intermediate lower compatible process flow; a flow check module creating a lower process flow including all the lower processes available in production facilities from the intermediate and intermediate lower compatible process flows based on an available process table; a flow selection module selecting the lower process flow by calculating an attribute based on an attribute definition table. An external storage unit stores the process decomposition table, the lower process compatibility table, the available process table, and the attribute definition table.

A manufacturing method is described for the preparation of optically active 1-(6-methoxy-2-naphthyl)-2-(alkoxycarbonyl)amino-1-propanone, its derivatives and their halo analogs. The optically active 1-(6-methoxy-2-naphthyl)-2-(alkoxycarbonyl)amino-1-propanone, its derivatives and their halo analogs are useful intermediates in the preparation of 2-(6-methoxy-2-naphthyl)propionic acid, which is useful as pharmaceutical, e.g. antiinflammatory, analgesic and anti-pyretic agents.
