Procedure

A solution of tert-butyl (3R)-6-cyclohexyl-3-{3-[7,8-dihydro[1,6]naphthyridin-6(5H)-ylcarbonyl]-1,2,4-oxadiazol-5-yl}hexanoate (Preparation 29) (281 mg, 0.58 mmol) in dichloromethane (4 ml) was treated with trifluoroacetic acid (1 ml) and the resulting mixture was stirred at room temperature under a nitrogen atmosphere for 17 hours. The solvent was removed under reduced pressure and the residue azeotroped from toluene to afford the title compound (245 mg).

Workup

  1. customThe solvent was removed under reduced pressure
  2. customthe residue azeotroped from toluene
