Phenylacetyl chloride → HCID 45111624, compound

Participants

Reaction Conditions

Reaction Steps

To an ice cold suspension of NaH (13 mg, 320 umol) in DMF (3 ml) under an argon atmosphere was added a solution of [2-(4-chloro-phenyl)-2H-indazol-3-yl]-cyclohexyl-amine (100 mg, 310 μmol; example 11.1) in DMF (1 ml) within 10 min. The suspension was stirred for 1 h at 0° C. A solution of phenyl-acetyl chloride (40 μl, 340 μmol; [103-80-0]) in DMF (1 ml) was added within 5 min. The reaction mixture was stirred for 14 h at ambient temperature, poured onto ice water/brine 1/1 and extracted two times with iPrOAc. The combined extracts were washed with ice water/brine 1/1 and dried over Na2SO4. The solvent was removed under reduced pressure and the residue was purified by preparative thin layer chromatography (silica gel, iPrOAc/heptane) to give the title compound (10 mg, 23 μmol; 7%) as off-white solid. MS: m/e=444.1 [M+H+].
