Komponenten

Versuchsvorschrift

To a solution of 6-bromo-1H-indazol-4-amine (available from Sinova, 300 mg, 1.41 mmol) in THF (7 ml), cooled to 0° C. was added 60% sodium hydride in mineral oil (62 mg, 1.55 mmol) and the reaction was stirred for 15 mins. Iodoethane (0.124 ml, 1.55 mmol) was added and the reaction was stirred overnight. The reaction was quenched with MeOH (1 ml), diluted with water (10 ml), then extracted into ethyl acetate, which was separated and evaporated to dryness. The residue was purified by silica chromatography using 0-100% ethyl acetate in cyclohexane over 80 mins. Pure fractions were evaporated to give the title compound (110 mg).
