Versuchsvorschrift

methyl 7-(4-((2-(4-chlorophenyl)cyclopropyl)carbamoyl)phenoxy)-6-cyano-3,4-dihydro-2H-chromene-4-carboxylate (50.7 mg, 0.101 mmol) was dissolved in THF (3 ml). A 1M solution of LiOH—H2O (0.202 ml, 0.202 mmol) was added and the mixture was stirred for 17 hours at ambient temperature. HCl (4M in dioxane) (0.0756 ml, 0.302 mmol) was added to the mixture. The solution was stirred additional 30 minutes and concentrated. The residue was purified on silica gel (MeOH in dichloromethane with 1% acetic acid gradient) to provide 47 mg of the title compound as a solid (95%). MS (apci) m/z=486.7 (M−H).
