Reaction Steps

(S)-4-Methyl-2-methylamino-pentanoic acid {2-[(4-benzyloxy-phenyl)-(3-methyl-but-2-enyl)-amino]-1,1-dimethyl-ethyl}-amide (XIIa, 0.14 g, 0.31 mmol) was dissolved in THF (10 mL), treated with diisopropylethylamine (0.31 g, 2.4 mmol), and 4-bromo-2-methyl-2-butene (0.6 mmol), and heated to 50° C. for 15 hours. The reaction was concentrated and chromatographed on silica gel eluting with 2:1 hexane/EtOAc to yield the desired product.
