Participants

Reaction Steps

To a solution of the compound (0.10 g) obtained in Example 33, step 1 in THF (3 mL)/diethyl ether (3 mL) was added tert-butyl isocyanate (41 μL), and the mixture was stirred at room temperature for 16 hr. The solvent was evaporated under reduced pressure, and the obtained solid was washed with diethyl ether/hexane to give tert-butyl 8-{4-[(tert-butylamino)carbonyl]piperazin-1-yl}-2,3-dihydropyrido[3,2-f][1,4]oxazepine-4(5H)-carboxylate (0.11 g, 85%) as a white powder.
