Det tilsettes så i små porsjoner 20 g 2-metoksy-5-benzosyre med en hastighet slik at temperaturen holdes mellom 10 og 15°C. Etter avsluttet tilsetning får reaksjonsblandingen anta romtemperatur som holdes i 1 time. Temperaturen bringes deretter gradvis til 60 - 70°C og holdes der i 1 time tilsvarende avsluttet gassutvikling. Blandingen avkjoles og den brune væske helles ut i en blanding av 60 ml vann og 2 50 g is. Det dannes et faststoff som frafiltreres og vaskes flere ganger med isblandet vann og torkes deretter under vakuum ved 80°C. 20 g of 2-methoxy-5-benzoic acid are then added in small portions at a rate such that the temperature is kept between 10 and 15°C. After the addition is complete, the reaction mixture is allowed to reach room temperature, which is maintained for 1 hour. The temperature is then gradually brought to 60 - 70°C and held there for 1 hour corresponding to the end of gas development. The mixture is cooled and the brown liquid is poured into a mixture of 60 ml of water and 250 g of ice. A solid is formed which is filtered off and washed several times with ice-cold water and then dried under vacuum at 80°C.

To the suspension, which is stirred vigorously, 130.8 g of zinc powder (2 mol) are added in portions over the course of approximately 2 hours so that the temperature is maintained at 15 - 20°C and the reaction mixture is cooled if necessary with an ice-mixed water bath.

Etter denne operasjon filtreres blandingen. Til filtratet tilsettes vann og under omroring 70 g ferriklorid. Omroringen fortsettes i 1 time hvoretter det utfelte produkt frafiltreres og vaskes tre ganger med vann. Produktet renses ved opplosning i en opplosning av natriumbikarbonat i nærvær av aktivkull, uopploselig substans fjernes ved filtrering og filtratet surgjores ved hjelp av saltsyre i overskudd, og det resulterende bunnfall filtreres og vaskes tre ganger med vann og torkes deretter. After this operation, the mixture is filtered. Water and, with stirring, 70 g of ferric chloride are added to the filtrate. Stirring is continued for 1 hour, after which the precipitated product is filtered off and washed three times with water. The product is purified by dissolving in a solution of sodium bicarbonate in the presence of activated carbon, insoluble matter is removed by filtration and the filtrate is acidified with excess hydrochloric acid, and the resulting precipitate is filtered and washed three times with water and then dried.
