반응 단계
To a solution of (R)-tert-butyl pyrrolidin-3-ylcarbamate (0.500 g) and 1,3-difluoropropan-2-one (0.278 g) in dichloromethane (5 mL) was added sodium triacetoxyborohydride (0.853 g). After stirring for 1 hour, the reaction was quenched with saturated NaHCO3 solution (5 mL). The product was extracted into dichloromethane (25 mL), dried over magnesium sulfate, filtered, and concentrated. The resulting crude material was treated with HCl (4.0M in dioxane, 4 mL) and methanol (1 mL) and stirred for 1 hour. The mixture was concentrated to provide the title compound.
