B. Benzo[b]thiophen-2-yl-carbamic acid tert-butyl ester (1d). A solution of 2-carboxybenzo[b]thiophene (14.4 g, 80.6 mmol), N,N-diisopropylethylamine (15.5 mL, 88.6 mmol) and diphenylphosphoryl azide (20.8 mL, 96.7 mmol) in t-butanol (150 mL) was heated at reflux for 8 hours. The solvent was evaporated under reduced pressure, and the residue was purified by flash column chromatography on silica gel, using dichloromethane as the eluant, to give the product as a colorless solid (18.9 g, 94%). 1H NMR (DMSO-d6): delta 1.50 (s, 9H), 6.78 (s, 1H), 7.16 (d of d, 1H), 7.27 (d of d, 1H), 7.58 (d, 1H) and 7.77 (d, 1H), 10.70 (br s, 1H); MS: m/z 250.2 (MH+).
As the paragraph descriping shows that 6314-28-9 is playing an increasingly important role.
