Reaction Steps

To a solution of 1,1-dimethylethyl (2-{[3′-(aminocarbonyl)-2-methyl-4-biphenylyl]oxy}ethyl)carbamate (0.090 g; 0.24 mmol; I-VII-2) and Et3SiH (0.1 mL; 0.6 mmol) in CH2Cl2 (5 mL) at room temperature was added TFA (1 mL) in one portion. The mixture was aged 2 h and concentrated in vacuo, affording the title compound as a pale yellow gum which was used without further purification. LC/MS (method A) 1.18 min, m/z 271 (M+H).
