Reaction Steps
To a solution of (1R,2S)-2-amino-1-(4-hydroxyphenyl)-propan-1-ol (495 mg) and ethyl N-[4-(2-bromoethyl)-2,6-dichloro-phenyl]aminoacetate (700 mg) in N,N-dimethylformamide (6 ml) was added N,N-diisopropylethylamine (343 μl), and the mixture was stirred for 7 hours at 70° C. The reaction mixture was concentrated in vacuo, and purification of the residue by medium pressure liquid column chromatography on aminopropyl silica gel (eluent: dichloro-methane/ethanol=20/1) gave ethyl N-[2,6-dichloro-4-[2-[[(1S, 2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]amino]-ethyl]phenyl]aminoacetate (510 mg).
