Procedure

About 10 g of AT-2266.hydrochloride was dissolved to hot water (about 70° C.) and the solution was neutralized with 15% aqueous solution of sodium hydroxide which was warmed to 70° C. previously. The precipitate was collected by filtration and dried at 70° to 80° C. for elimination of adhering water to give the AT-2266.sesquihydrate.

Workup

  1. filtrationThe precipitate was collected by filtration
  2. dry with materialdried at 70° to 80° C. for elimination of adhering water
