Reaction Conditions

Reaction Steps

The synthesis was carried out on 0.15 g of PL Wang resin (1.7 mmol/g). The attachment of 2-amino-indane-2-carboxylic acid and the acylation with 3-hydroxy-4-methylbenzoic acid were performed as in described in example 173. After the acylation step, the resin was washed with THF and a solution of triphenylphosphine (10 equivalents) and 2-(3-chlorophenyl)-ethanol (10 equivalents) in THF was added to the resin. The slurry was cooled to 0° C., DIAD (10 equivalents) was added to the cooled mixture, and the reaction mixture was shaken overnight at room temperature. The resin was washed with DCM. The compound was cleaved, isolated and purified as in described in example 173. Yield: 2.3 mg.
