Reaction Steps

At RT, 2.23 g (19.0 mmol) of tert-butyl carbamate and 6.25 g (38.1 mmol) of benzenesulphinic acid sodium salt were initially charged in 55 ml of methanol/water (1:2), and 5.00 g (28.6 mmol) of 2,3-dichlorobenzaldehyd and then 1.43 ml (37.9 mmol) of formic acid were added. The reaction mixture was stirred at RT for 2 days. The precipitated solid was filtered off with suction and washed with water and twice with diethyl ether. From the ethereal filtrate, 3.47 g of 2,3-dichlorobenzaldehyde were recovered after removal of the solvent on a rotary evaporator. The solid which was filtered off with suction was dried under high vacuum. This gave 2.22 g (19% of theory) of the title compound.
