PROCEDURE

实验过程

1 g of 3-(3-{2-[(E)-3,5-Diamino-6-chloro-pyrazine-2-carbonylimino]-1,3,8-triaza-spiro[4.5]decane-8-carbonyl}-benzenesulfonylamino)-propionic acid dipropylcarbamoylmethyl ester (may be prepared as in Preparation 1) and 0.18 g succinic acid were dissolved in 7.97 g methanol in a glass vial at 50° C. The solution was cooled to 0° C. and then stirred at that temperature for 24 hours. Afterwards, crystals were collected by filtration and dried at 60° C. and 1 mbar for 3 hours. Off-white to yellowish crystals of form C were obtained.
