Reaction Steps

To a solution of 4-((2S,3S)-7-carbamoyl-1,1-diethyl-3-methoxy-1,2,3,4-tetrahydro-naphthalen-2-ylamino)-2-(trans-4-hydroxy-cyclohexylmethyl)-butyric acid methyl ester (f1) (27.4 mg, 0.045 mmol) in MeOH (0.50 mL) was added water (32 μL) and 10N NaOH (32 μL, 0.32 mmol). The mixture was heated at 50° C. After 15 h, the reaction mixture was cooled to RT, dissolved in 50% aqueous AcOH (6 mL) and purified by preparative HPLC to give the title compound (13.8 mg) as a lyophylized powder.
