Procedure

In a similar manner to that described for the preparation of [(S)-1-(5-bromo-2-methoxy-naphthalen-1-ylmethyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl]-carbamic acid tert-butyl ester (Intermediate 5), ((S)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl)-carbamic acid tert-butyl ester (Intermediate 4)(400 mg, 1.44 mmol) and 1-bromomethyl-2-methoxy-naphthalene (435.15 mg, 1.733 mmol) were converted to the title compound (450 mg, 69.6%) which was obtained as a white solid. LC-MS 448 (M+H).
