Acetic Acid → HCID 57293869, compound

Participants

Reaction Steps

209 μl (0.936 mmol) of phenylacetaldehyde are added dropwise over the course of 10 minutes to a solution of 100 mg (0.233 mmol) of (2R*,4S*)-2-benzyl-N-(4-quinolylmethyl)-N-trifluoroacetyl-4-piperidinamine, 58 mg (0.702 mmol) of sodium acetate, 44 mg (0.702 mmol) of sodium cyanoborohydride and 67 μl (1.17 mmol) of acetic acid in 2 ml of ethanol at room temperature. The reaction mixture is left to stir at room temperature for 16 hours. The residue after evaporation in a rotary evaporator is taken up in ethyl acetate, and the organic phase is washed with water and with brine, dried over magnesium sulfate and evaporated to dryness. The yellow oil is chromatographed on silica gel with methylene chloride/methanol/conc. ammonia (2000:50:1). The title compound is obtained as oil. TLC: methylene chloride/methanol/conc. ammonia (2000:50:1) Rf =0.33, FD-MS: M+ =531.
