実験手順

In a similar manner to that described for Example 36 Step 1 except 4 equivalents of DIEA were used, (2S,3S)-3-amino-2-methyl-7-(trifluoromethyl)-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one trifluoroacetate (58 mg, 0.155 mmol) and (S)-2-(tert-butoxycarbonyl(methyl)amino)propanoic acid (31.5 mg, 155 μmol) were converted to a material which was purified by silica gel chromatography to afford methyl-[(S)-1-((6S,7S)-6-methyl-8-oxo-2-trifluoromethyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-7-ylcarbamoyl)-ethyl]-carbamic acid tert-butyl ester (52 mg, 75%)
