Acetic Acid → HCID 67007458, compound

Participants

Reaction Steps

300 mg of (S)-1-{2-[1-(4-fluorophenyl)ethylamino]-6-(pyrazin-2-ylamino)pyrimidin-4-yl}azetidin-3-one was dissolved in 5 ml of 1,2-dichloroethane, and 12 ml of 2M dimethylamine/tetrahydrofuran solution and 290 μl of acetic acid were added thereto, and the mixture was stirred at room temperature for 30 minutes. 340 mg of sodium triacetoxyborohydride was added thereto, and the mixture was stirred at room temperature overnight. The reaction solution was diluted with ethyl acetate. The solution was washed in turn with a saturated aqueous solution of sodium bicarbonate and brine, and then dried over sodium sulfate. The solvent was distilled off under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 187 mg of the objective compound as brown powder.
