3.2 g (16.5 moles) of 4-carbomethoxybenzothiamide and 4.2 g (16 millimoles) of 6-chloroacetyl-1,2,3,4-tetrahydro-1,1,4,4-tetramethylnaphthalene (for preparation see Example 28) in 40 ml of isopropanol were refluxed for 1 hour with the addition of 2 drops of pyridine. The mixture was cooled, water was added and the crystals formed were filtered off under suction. Recrystallization from isopropanol and a trace of water gave 3.0 g the title compound of melting point 138°-140° C.
