Reaction Steps

The title compound was prepared analogously to the synthesis of Intermediates 5 and 6 in three steps by coupling commercially available (1S,2S)-1-[(tert-butoxycarbonyl)amino]-2-phenylcyclopropanecarboxylic acid 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.
