Reaction Steps
The title compound was prepared analogously to the synthesis of Intermediates 5 and 6 in three steps by coupling commercially available N-(tert-butoxycarbonyl)-3-methyl-L-valine 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.
