Quantities of 2.78 g (23.7 mmol) of tert-butyl carbamate and 7.79 g (47.4 mmol) of benzenesulphinic acid sodium salt were introduced in 55 ml of methanol/water 1:2 at RT and admixed with 5 g (35.6 mmol) of 2-chlorobenzaldehyde and then with 1.78 ml (47.1 mmol) of formic acid. The mixture was stirred at RT for 2 days. The white solid precipitated was filtered off with suction and washed in succession twice each with water and diethyl ether. Drying in an HV gave 5.77 g (42% of theory) of the title compound.
