Reaction Steps

DIEA (712 mg, 972 μl, 5.51 mmol, Eq: 5.00) was added to a mixture of (S)-methyl 3-amino-5-((6-bromo-2-methoxynaphthalen-1-yl)methyl)-4-oxo-2,3,4,5-tetrahydrobenzo[b][1,4]oxazepine-9-carboxylate trifluoroacetate (660 mg, 1.1 mmol, Eq: 1.00), (S)-2-(tert-butoxycarbonyl(methyl)amino)propanoic acid (224 mg, 1.1 mmol, Eq: 1.0), HBTU (418 mg, 1.1 mmol, Eq: 1.0) and HOBT.H2O (149 mg, 1.1 mmol, Eq: 1.0) in DMF (12.5 mL) at 0° C. The mixture was warmed to RT, stirred for 1 h, diluted with EtOAc, washed with H2O, brine and dried over Na2SO4. The mixture was filtered and concentrated to afford the title compound (725 mg, 98%) as an off-white foam which was used without purification.
