실험 절차

A solution of 1-[[2-(diethylamino)ethyl]amino]-7-methoxy-9-oxothioxanthen-4-carboxaldehyde (3 g, 7.8 mmol ) and 1.5 mL of formic acid in 25.5 mL of N-methylformamide was heated to 170° C. for 8 h with stirring under nitrogen. The reaction mixture was poured into 160 mL of ice/water, basified with 35% of NaOH solution, and extracted into chloroform (3×). The organic layer was washed with water (2×) and brine, dried over sodium sulfate, and the solvent was removed in vacuo affording 3 g (89.9 %) of the desired N-[[1-[[2-(diethylamino)ethyl]amino]-7-methoxy-9-oxothioxanthen-4-yl]methyl]-N-methylformamide (Formula IV: R1 =R2 =Et; R4 =Me; R8 =7-OCH3 ; n=2).
