Sodium Hydroxide → 3-(1-{5-[6-(4-Methyl-pyridin-2-ylamino)pyridin-2-yl]thiazol-2-yl}piperidin-4-yl)propionic acid

Participants

Reaction Steps

To a mixed solution of 3-(1-{5-[6-(4-methyl-pyridin-2-ylamino)pyridin-2-yl]thiazol-2-yl}piperidine-4-)propionic acid methyl ester (250 mg, 0.57 mmol) obtained in Step 3 in tetrahydrofuran (5 ml) and methanol (5 ml), 4N sodium hydroxide (1.5 ml, 6.0 mmol) was added and the mixture was stirred at room temperature for 12 hours. The concentrate obtained by concentrating the reaction solution in vacuo was neutralized with 0.1N hydrochloric acid, and the precipitated solid was collected by filtration, washed with water and the title compound (142 mg, 59%) was obtained.
