実験手順

A solution of biphenyl-2-ylcarbamic acid 1-[2-(4-formyl-2,5-dimethylphenylcarbamoyl)ethyl]piperidin-4-yl ester (150 mg, 0.30 mmol) and N-{5-[(R)-2-amino-1-(tert-butyldimethylsilanyloxy)ethyl]-2-hydroxyphenyl}formamide (112 mg, 0.36 mmol) in a 1:1 mixture of dichloromethane and methanol (3.0 mL total) was stirred at room temperature for 30 minutes. Sodium triacetoxyborohydride (191 mg, 0.9 mmol) was added and the resulting mixture was stirred at room temperature overnight. Acetic acid was added to quench the reaction and the mixture was concentrated under reduced pressure to give biphenyl-2-ylcarbamic acid 1-[2-(4-{[(R)-2-(tert-butyldimethylsilanyloxy)-2-(3-formylamino-4-hydroxyphenyl)ethylamino]methyl}-2,5-dimethylphenylcarbamoyl)-ethyl]piperidin-4-yl ester, which was used without further purification. LCMS (10-70) Rt=4.55; [M+H+] found 794.6.
