実験手順

200 mg (0.48 mmol) of the compound of step 2 were dissolved in 5 ml of methanol, 13.1 mg (0.1 mmol) of potassium carbonate were added and the mixture was stirred for 30 min. The mixture was acidified with 1 N hydrochloric acid and extracted three times with 20 ml portions of EA. The combined organic phases were dried and evaporated. The residue was dissolved in 5 ml of THF, 96.9 mg (0.71 mmol) of 2-(3-methylphenyl)-ethanol and 186.7 mg (0.71 mmol) of triphenylphosphine were added, the mixture was cooled in an ice bath, and 191.9 mg (0.95 mmol) of DIAD were added. After stirring overnight, the mixture was evaporated to dryness and the residue was purified by preparative RP HPLC (water/ACN gradient). 104 mg of the title compound were obtained.
