Procedure

10.00 g of metformin hydrochloride, 2.40 g of sodium hydroxide and 2.20 g of adipic acid were stirred in 150 ml of ethyl alcohol at 70° C., and then methylene chloride was added thereto. Then, the produced inorganic salt was filtered, and ethyl acetate was added to the filtrate. The produced crystal was filtered and dried in hot air, thus obtaining 4.90 g (yield: 80.5%) of metformin adipate.
