Reaction Steps
A solution of 7-(4-tert-butyl-cyclohexylcarbamoyl)-1-cyclopentylmethyl-isoquinoline-3-carboxylic acid (65 mg, 0.148 mmol) in DMF(1.5 mL) was treated with (2S)-amino-3,3-dimethyl-butyric acid methyl ester HCL (35 mg, 0.193 mmol), HBTU (73 mg), and DIEA (0.106 mL) by the General Procedure A. The crude product was purified by flash column chromatography on silica gel using 88:12 Hexanes/EtOAc to give 18 mg of 2(S)-{[7-(4-tert-butyl-cyclohexylcarbamoyl)-1-cyclopentylmethyl-isoquinoline-3-carbonyl]-amino}3,3-dimethylbutyric acid methyl ester as a colorless oil. This was used for the next step.
