p-Toluenesulfonic acid monohydrate → (S)-4-(1-(5-Fluoropyridin-2-yl)ethylamino)-2-(2-methoxypyridin-3-ylamino) pyrimidine-5-carboxamide

Participants

Reaction Steps

A solution of (S)-2-(1H-benzo[d][1,2,3]triazol-1-yloxy)-4-(1-(5-fluoropyridin-2-yl) ethyl amino)pyrimidine-5-carboxamide (Preparation 5c, 30 mg, 0.08 mmol), 2-methoxy pyridin-3-amine (14 mg, 0.11 mmol) and p-toluenesulfonic acid hydrate (15 mg, 0.08 mmol) in 1,4-dioxane (3 mL) was heated at 120° C. for 4 hours. The solvent was evaporated under reduced pressure and the resulting residue was purified by reverse phase chromatography (C-18 silica from Waters©, water/acetonitrile/methanol as eluents [0.1% v/v formic acid buffered] 0% to 100%) to give the title compound (21 mg, 72%) as a solid.
