실험 절차

To a solution of guanidine hydrochloride (463 mg) in N,N-dimethylformamide (20 ml) was added 28% sodium ethoxide (0.22 ml) under ice-cooling, and the mixture was stirred at room temperature for 5 minutes. To the resulting mixture was added 2-[8-[(2S)-2-hydroxy-3-phenoxypropyl]amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-yloxy]acetic acid ethyl ester (400 mg). After being stirred at room temperature for 2 hours, the precipitates were collected by filtration and treated with 4N hydrogen chloride in ethyl acetate to afford N-[2-[8-[(2S)-2-hydroxy-3-phenoxypropyl]amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-yloxy]acetyl]guanidine hydrochloride (243 mg).
