The invention discloses a preparation method of methanesulfonic acid camostat. The method comprises the following steps: dimethylamine reacts with chloroacetyl chloride to obtain 3-pyrrolidone hydrochloride, a 3-pyrrolidone hydrochloride crude product is added with hydroxyphenylacetic acid and triethylamine to obtain methanesulfonic acid camostat, and a methanesulfonic acid camostat product is prepared from the obtained methanesulfonic acid camostat. The methanesulfonic acid camostat prepared by adopting the method is good in quality, high in yield, less in energy consumption and low in cost, and meanwhile, the preparation method is simple.
