実験手順

A mixture of (R)-3-cyclopropylmethanesulfonyl-2-[(morpholine-4-carbonyl)-amino]-propionic acid (0.352 g, 1.1 mmol) and N-cyclohexylcarbodiimide N′-methylpolystyrene (1.93 mmol/g, 1.03 g) in DCM (10 mL) was treated with hydroxybenzotriazole (0.27 g, 2 mmol). After stirring at room temperature for 5 minutes the mixture was treated with 2-amino-cyclohexane-1,3-diol (0.0.13 g, 1 mmol) and stirring was continued for a further 2 days. The reaction mixture was treated with PS Trisamine (3.75 mmol/g, 1.3 g) and after stirring at room temperature for 2 hours the resin was filtered off and washed with DCM. The combined filtrate plus washings were evaporated under reduced pressure to give morpholine-4-carboxylic acid [(R)-2-cyclopropylmethanesulfonyl-1-(2,6-dihydroxy-cyclohexylcarbamoyl)-ethyl]-amide (0.32 g) as pale yellow thick oil. MS: 434 (MH+).
