실험 절차

5-[1-Methyl-4-(2-trimethylsilanyl-ethoxymethoxy)-1H-indol-6-ylmethyl]-pyrimidine-2,4-diamine. A warm solution of potassium tert-butylate (2.68 g, 23.4 mmol) in tert-butanol (20 mL) was added to a room temperature solution of 1-methyl-4-(2-trimethylsilanyl-ethoxymethoxy)-1H-indole-6-carbaldehyde (5.95 g, 19.5 mmol) and 3-anilinopropionitrile (3.20 g, 21.4 mmol) in methyl sulfoxide (70 mL). After 2 h the solution was diluted with ethyl acetate, washed with water and brine, dried (MgSO4), and evaporated. This material was dissolved in ethanol (70 mL) and added to a suspension of guanidine hydrochloride (6.21 g, 64.4 mmol) in ethanol (210 mL), and the mixture was stirred at 70° C. for 22 h. Most of the solvent was distilled off, and the residue was partitioned between water and ether. The organic layer was washed with brine, dried (MgSO4), and evaporated. Flash chromatography (SiO2; CH2CL2/MeOH/NH4OH 19:1:0.05) afforded the title compound (3.32 g, 43%).Yellow solid.
