Reaction Steps

A mixture of 1-[[2-(diethylamino)ethyl]amino]-7-methoxy-9-oxothioxanthen-4-carboxaldehyde (3.6 g, 0.0094 mol), formamide (48 mL) and formic acid (6 mL) was heated to 170° C. under N2 for 8 hours. The mixture was poured into ice-water, basified with 35% NaOH and extracted with chloroform. The organic layer was separated, washed with water (2x), then brine and was dried over Na2SO4 and concentrated in vacuo to afford 3.88 g of N-[[1-[[2-(diethylamino)ethyl]amino]-7-methoxy-9-oxothioxanthen-4-yl]methyl]-N-methylformamide.
