Reaction Steps

(9aS)-8-[1-(Diphenylmethyl)azetidin-3-yl]hexahydropyrazino-[2,1-c][1,4]oxazin-4(3H)-one (85 mg, 0.22 mmol) was dissolved in ethanol (18 mL). The solution was transferred to a 25 mL vial, which contained ethanol (2 mL), 10% palladium on carbon (0.1 g), formic acid (0.1 g, 2.2 mmol) and ammonium formate (0.2 g, 3.17 mmol). The mixture was heated for 5 min at 120° C. using microwave single node heating. The catalyst was filtered off and the solution of crude (9aS)-8-azetidin-3-ylhexahydropyrazino[2,1-c][1,4]oxazin-4(3H)-one was used in the next step without purification and quantification.
