methyl 4-morpholin-4-ylbutanoate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 15 g. (0.052 mole) of Methyl γ-morpholinobutyrate (Cruickshank and Sheehan, J. Am. Chem. Soc. 83, 2891 (1961)) was dissolved in a mixture of 45 ml. of 47% hydrobromic acid and 45 ml. of water and heated for 16 hours at reflux. The solution was taken to dryness under reduced pressure, and the solid which formed was triturated with acetone. The material was filtered and crystallized from 60 ml. of acetic acid to give 12.4 g. (95%) of product as colorless crystals, m.p. 151°-152.5°C. The infrared and nuclear magnetic resonance spectra were consistent with the proposed structure. at reflux the solid which formed was triturated with acetone The material was filtered crystallized from 60 ml of acetic acid to give 12.4 g
