実験手順

The title compound was prepared analogously to the synthesis of Intermediates 5 and 6 in three steps by coupling commercially available N-(tert-butoxycarbonyl)-β-phenyl-L-phenylalanine with 1,2-oxazinane hydrochloride (Starting Material 5), subsequent deprotection with trifluoroacetic acid and another coupling with Starting Material 1. The end product was purified by preparative HPLC.
