Application
TCI Practical Example: Protection of the Boronic Acid with 1,8-Diaminonaphthalene
Used Chemicals
Procedure
To a reaction vessel, 1,8-diaminonaphthalene (1.5 g, 9.5 mmol), 3,5-dibromophenyl boronic acid (2.5 g, 8.9 mmol), toluene (30 mL) were subsequently added and refluxed for 2 hours. Consumption of the starting material was confirmed by TLC. The reaction mixture was cooled to room temperature and was filtered under reduced pressure. The solid was washed with toluene to obtain 1 (2.9 g, 81% yield) as a reddish white powder.
Experimenter’s Comments
The reaction mixture was monitored by TLC (hexane:ethyl acetate = 4:1, Rf = 0.5).
Analytical Data
1H NMR (400 MHz, CDCl3); δ 7.76 (t, 1H, J = 1.8 Hz), 7.67 (d, 2H, J = 1.8 Hz), 7.15 (m, 2H), 7.08 (m, 2H), 6.42 (d, 2H, J = 7.3 Hz), 5.94 (br, 2H).
