Morpholine → (5-Morpholinopyridin-2-yl)methanol

온도

110 °C

In a 10 mL Microwave vial was (5-bromopyridin-2-yl)methanol (500 mg, 2.66 mmol), morpholine (0.233 mL, 2.66 mmol),cesium carbonate (2166 mg, 6.65 mmol), Pd2(dba)3 (60.9 mg, 0.07 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (115 mg, 0.20 mmol) in dioxane (10 mL) () to give a brown suspension. The reaction mixture was heated to 110 °C for 3h. The reaction mixture was passed over Celite and washed with ethylacetate. The Filtrate was concentrate to dryness to get as a syrupy brown liquid. Water 30ml was added and extracted with ethylacetate (20x 2)ml. THe organic layers are collected, dried over Sodium Sulphate and concentrated to get as a liquid. The crude product was added to a silica gel column and was eluted with ethylacetate 0-70% Pure Collected fractions are evaporated to get as a (5-morpholinopyridin-2-yl)methanol (100 mg, 19.36 %)colorless liquid . The compound was carried to next step.
