Reaction Steps

In a solution of ethanol (19.5 ml) and water (1.2 ml) was dissolved (-)-4-[N-(3-methoxypropyl)-N-pentylcarbamoyl]-5-(2-naphthylsulfonyl)pentanoic acid (7.80 g) and L-arginine (2.84 g) with stirring at 40° C. Insoluble materials (e.g. trash) were collected by filtration and washed with a mixture of ethanol (7 ml) and water (1.3 ml). After combining the filtrate and washing, the mixture was allowed to stand at room temperature, and the precipitated crystals were collected by filtration to obtain 9.80 g of L-arginine (-)-4-[N-(3-methoxypropyl)-N-pentylcarbamoyl]-5-(2-naphthylsulfonyl)pentanoic acid monohydrate.
