실험 절차

Methanol (120 ml) was added to a mixture of intermediate (5) (2.35 g) and K2CO3 (9.19 g) in water (40 ml). The resulting reaction mixture was stirred and refluxed for 19 hours under argon. Water (120 ml) was added, the precipitate was filtered off and purified by column chromatography over silica gel (eluent: DCM/2-propanone 90/10). Two desired fractions were collected and their solvent was evaporated. The first fraction group was slurried in ACN, cooled, filtered off and dried, yielding 0.75 g (45%, white solid) of 4-[[4-amino-6-[(5-chloro-1H-indol-4-yl)methyl]-1,3,5-triazin-2-yl]amino]benzonitrile (compound 8, mp. 267-268° C.). The second column fraction group yielded 0.15 g of 4-[[4-amino-6-[(5-chloro-1H-indol-4-yl)methyl]-1,3,5-triazin-2-yl]amino]benzamide (compound 9). After 24 hours at RT the aqueous filtrate was filtered to give 0.25 g of compound (9). The two fractions of compound 9 were combined, dissolved in 500 ml of refluxing methanol, hot filtered, the filtrate concentrated to 50 ml, cooled and filtered, then dried, yielding 0.25 g (14%) of 4-[[4-amino-6-[(5-chloro-1H-indol-4-yl)methyl]-1,3,5-triazin-2-yl]amino]benzamide (compound 9, mp. 204-205° C.).
