Participants

Reaction Steps

0.6 g (1.87 mmol) of 3-{3-[3-(4-chlorophenyl)isoxazol-5-yl]propyl}-1,3-oxazolidine-2,4-dione, prepared in stage 4.2., is dissolved in a mixture of 8 ml of tetrahydrofuran and of 15 ml of methanol. 2.8 ml of a 2M solution of methylamine (5.6 mmol) in tetrahydrofuran are added. Reaction is allowed to take place at ambient temperature overnight and then the mixture is evaporated. The residue is purified by chromatography on silica gel, elution being carried out with a 98/2 and then 95/5 and 90/10 mixture of dichloromethane and of methanol. The product is recrystallized from a mixture of ethyl acetate and of methanol to produce 0.49 g (1.4 mmol) of white crystals.
