Procedure

Add N,N-diisopropylcarbodiimide (0.114 g, 0.902 mmol) to a solution of 5-[[4-(4-acetyl-3-hydroxy-2-propyl-phenoxymethyl)-phenyl]-(tetrahydro-pyran-2-yloxy)-methyl]-2-methoxy-benzoic acid (0.450 g, 0.820 mmol) and 1-hydroxybenzotriazole hydrate (0.122 g, 0.902 mmol) in dichloromethane (0.2M). Stir the solution for 1 h at room temperature. Saturate the solution with ammonia gas and stir the solution for 24 h. Collect the precipitate as the title compound (0.440 g, 0.815 mmol, 98%): MS (m/z): 546 (M−1).
