実験手順
To a stirred solution of the compound obtained from example 19 (36 mg, 0.1 mmol) in methanol (2 mL) cooled to 0° C. was added TMS-Cl (25 μL, 0.2 mmol). After 30 minutes, the volatiles were removed under reduced pressure and the residue was triturated several times with ether to obtain the hydrochloride salt of (2S)-1-{N-[2-(2-oxopyrrolidin-1-yl)hexahydro-2,5-methanopentalen-3a(1H)-yl]glycyl}pyrrolidine-2-carbonitrile as off-white solid (38 mg).
