实验步骤: The above resin bound (R)-3-(4-formylbenzoylamino)-2-hydroxypropionic acid was treated with a 0.5 M solution of 4-tert-butylcyclohexylamine (0.25 mmol) in a mixture of N-methyl-2-pyrrolidinone and trimethylorthoformate (1:1, 0.5 mL) and glacial acetic acid (50 μL) for 1 hour at 25° C. Sodium cyanoborohydride (250 μmol, 16 mg) dissolved in a mixture of N-methyl-2-pyrrolidinone and methanol (1:1, 0.25 mL) was added and the mixture was vortexed at 25° C. for 4 hours followed by filtration and washing with a mixture of N-methyl-2-pyrrolidinone and methanol (1:1, 2×1 mL) 3×1 mL N-methyl-2-pyrrolidinone (3×1 mL) and a mixture of 1,2-dichloropropane and diisopropylethylamine (7:1, 2×0.75 mL). was added followed by filtration washing with a mixture of N-methyl-2-pyrrolidinone and methanol (1:1, 2×1 mL) 3×1 mL N-methyl-2-pyrrolidinone (3×1 mL) a mixture of 1,2-dichloropropane and diisopropylethylamine (7:1, 2×0.75 mL)
