Participants

Reaction Steps

Formaldehyde (37% aq. sol., 0.4 ml) and sodium cyanoboron hydride (138 mg) were successively added to an acetonitrile suspension (3 ml) of 400 mg of the (S)-N-{3-[3-fluoro-4-(4-methylamino-piperidin-1-yl)-phenyl]-2-oxo-oxazolidin-5-ylmethyl}-acetamide (Compound No. 70) which was synthesized in Example 18, and the mixture was stirred at room temperature for 48 h. Methanol was added and the mixture was stirred for 10 min. Thereafter, alumina (5 g) was added and the residue was evaporated under vacuum. The residue was purified by alumina column chromatography (solvent: chloroform/methanol=100/1) to afford the title compound (363 mg) in a yield of 87%.
