Participants

Reaction Steps

A solution of 2-[3,6dimethyl-1-(2,4,6-trimethylphenyl)-1H-pyrazolo[3,4-b]pyridin-4-ylamino]-butan-1-ol (69 mg, 0.196 mmol) in 1 ml of dry tetrahydrofuran was treated with 60% sodium hydride oil (28 mg, 0.7 mmol). After stirring for 3 minutes, methyliodide (0.3 ml) was added and the mixture was stirred at room temperature for 1.5 hours. The mixture was quenched with water and extracted with ether. The organic layer was washed with water, dried and concentrated to give 61 mg of crude material. The residue was purified through silica gel column chromatography using chloroform as eluent to give 43 mg of the title compound in yellow glass form. 1H NMR (CDCl3): 6.91 (s, 2H), 6.00 (s, 1H), 5.05 (d, 1H), 3.4-3.6 (m, 2h), 3.41 (s, 3H), 2.66 (s, 3H), 2.28 (s, 3H), 1.92 (s, 3H), 1.91 (s, 3H), 1.6-1.8 (m, 2H), 1.05 (t, 3H), ppm; IR (CHCl3) 2920, 1586 cm−1; High MS calc. 366.2413, found 3.66.24516. The glass form was converted to the corresponding HCl salt form as a yellow solid.
