Participants

Reaction Steps

Under argon, 80 mg (0.19 mmol) of the compound from example 31 was largely dissolved in 2 ml THF, 32.5 mg (0.29 mmol) of 3,3,3-trifluoropropan-1-ol, 75 mg (0.29 mmol) of triphenyl phosphine and 56 μl (0.29 mmol) of diisopropyl azodicarboxylate were added and it was stirred for 3 d at RT. A further 11 mg (0.01 mmol) of 3,3,3-trifluoropropan-1-ol, 25 mg (0.01 mmol) of triphenyl phosphine and 19 μl (0.01 mmol) of diisopropyl azodicarboxylate were added and it was stirred for 1 d at RT. The reaction mixture was concentrated by evaporation and the residue was purified by preparative HPLC (Reprosil C18, gradient of acetonitrile/0.01% aq. formic acid). Yield: 48 mg (49% of theor.)
