Reaction Steps

The crude (1R,2S)-ethyl 1-(6-(3-chlorophenoxy)-2-((S)-2-(4-fluorophenylamino)-3,3-dimethylbutanoyl)-1,2,3,4-tetrahydroisoquinoline-3-carboxamido)-2-vinylcyclopropanecarboxylate (130 mg, 0.20 mmol) was dissolved in 1.0 mL of a mixture of THF:MeOH:H2O (2:1:1). Lithium hydroxide monohydrate (0.050 g, 1.2 mmol) was added and reaction stirred at rt overnight. The reaction was then concentrated under vacuum and quenched with 5 mL of 1 N HCl. The product precipitated and could be filtered off giving an off-white powder (110 mg). It was directly used in the next step without further purification. MS m/e 619 (M−−H).
