Reaction Steps
A mixture of 5′-tert-butoxycarbonylamino-2′-methyl-biphenyl-4-carboxylic acid (500 mg), 4-(1,1-dioxo-1lambda*6*-thiomorpholin-4-ylmethyl) -phenylamine (367 mg), triethylamine (0.64 ml) and O-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophosphate (869 mg) in dry DMF (20 ml) was stirred at 20 C for 118 h. The mixture was then partitioned between water and dichloromethane. The dried extracts were evaporated and the residue purified on silica gel. Elution with ethyl acetate:petrol; 1:1 removed high Rf impurities and further elution with ethyl acetate gave the title compound as a pale yellow solid (693 mg).
