Reaction Steps

At 0° C., a mixture of 30 mg (0.082 mmol) of N-({3-[4-(aminomethyl)phenyl]-2-oxo-1,3-oxazolidin-5-yl}methyl)-5-chloro-2-thiophene-carboxamide (from Example 148) in 1.5 ml of absolute THF and 1.0 ml of absolute dichloromethane, and 0.02 ml of absolute pyridine is mixed with acetic anhydride (0.015 ml, 0.164 mmol). The mixture is stirred at room temperature overnight. Addition of ether and crystallization affords the product. Yield: 30 mg (87% of theory),
