Potassium sodium tartarate → 5-(4-Chlorophenyl)-2-({1-[1-(2-chlorophenyl)-2-hydroxyethyl]-1H-1,2,3-triazol-4-yl}methyl)-4-[(2S)-3,3,3-trifluoro-2-hydroxypropyl]-2,4-dihydro-3H-1,2,4-triazol-3-one

Participants

Reaction Steps

48 mg (0.084 mmol) of the compound from Example 103 were dissolved in 2 ml of THF, and 88 μl (0.088 mmol) of a 1 M solution of lithium aluminum hydride in THF were added at −10° C. After the addition had ended, the mixture was stirred at RT for 1 h. For work-up, 2 ml of saturated aqueous sodium potassium tartrate solution were added at RT, and the mixture was extracted with 5 ml of ethyl acetate. The organic phase was washed once with 5 ml of saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated under reduced pressure. The crude product was purified chromatographically [Method 19]. This gave 8 mg (18% of theory) of the target compound.
