実験手順
0.18 g of N-[8-(4-chloro-N-{[(2S,4R)-4-hydroxypyrrolidin-2-yl]methyl}-D-phenylalanyl)-8-azabicyclo[3.2.1]oct-3-yl]-N-cyclohexyl-N′,N′-diethylurea is placed in 0.4 ml of 2N hydrochloric acid in diethyl ether. Trituration, rinsing with diethyl ether, and filter-drying of the precipitate obtained are carried out. 0.16 g of N-[8-(4-chloro-N-{[(2S,4R)-4-hydroxypyrrolidin-2-yl]methyl}-D-phenylalanyl)-8-azabicyclo-[3.2.1]oct-3-yl]-N-cyclohexyl-N′,N′-diethylurea hydrochloride is obtained.
