Reaction Steps

A mixture of 1-(4-(2-methylpyrimidin-5-yl)tetrahydro-2H-pyran-4-yl)ethanone (300 mg, 1.35 mmol), saturated NH4OAc in EtOH (15 mL) and aq.NH3 (5 mL) was added NaCNBH3 (255 mg, 4.05 mmol) and heated to reflux overnight. The EtOH was removed. The residue was extracted with EtOAc (5×10 mL) and the organic layer was discarded. The precipitation of solid was collected by filtration from the aqueous layer after 16 hours to give 1-(4-(2-methylpyrimidin-5-yl)tetrahydro-2H-pyran-4-yl)ethanamine (100 mg, yield: 33.3%). 1H NMR (DMSO-d6 400 MHz): c58.67 (s, 2H), 3.80-3.65 (m, 2H), 3.20-3.05 (m, 2H), 2.63 (s, 3H), 2.45-2.35 (m, 1H), 2.35-2.25 (m, 2H), 1.81-1.70 (m, 2H), 0.87 (d, J=6.4 Hz, 3H).
