生成物 1

HCID 210716106-phenoxy-1H-indole

実験手順

Combine 4-phenoxy-1-methyl-2-nitro-benzene (6 g, 26.2 mmol) and DMF dimethylacetal (15.6 g, 131 mmol) in 60 mL dry DMF and heat at 170° C. for 16 hours. Cool to room temperature and concentrate to dryness. Dissolve residue in 50 mL EtOAc and hydrogenate with 2 g 5% Pd/C and hydrogen for 3 hours at atmospheric pressure. Filter through celite and concentrate to an oil. Purify by chromatography using Hex/EtoAC to obtain a tan solid: ISMS 210 (M+1)
