Procedure

500 mg (1.8 mmol) of 5-methyl-5-(3-cyclopropylmethoxy-4-methoxyphenyl)-2-oxazolidinone was first stirred with 75 mg (3.1 mmol) of sodium hydride in 17 ml of dimethylformamide for 30 minutes and, after adding 0.25 ml (2.7 mmol) of isopropyl bromide, for 17 hours at room temperature. The process was continued analogously to Example 1, thus obtaining 169 mg of 5-methyl-5-(3-cyclopropylmethoxy-4-methoxyphenyl)-3-isopropyl-2-oxazolidinone as an oil.
