Reaction Steps

132 mg (0.45 mmole) of N-(3-Amino-1-adamantyl)-4-methoxybenzamide are reacted with 87 mg (0.42 mmole) of (2S)-1-(chloroacetyl)-4,4-difluoro-pyrrolidine-2-carbonitrile in the presence 340 mg (1.32 mmole) PS-DIEA in 25 ml acetonitrile, as described in Example 2/b.). After work-up and chromatographic purification (chloroform-methanol-25% aqueous ammonia solution 9:1:0.1) and acidification ethereal hydrochloride acide the title compound is obtained: 90 mg (46%).
