실험 절차

5-Methyl-3-(pyrazolo[1,5-a]pyrimidin-5-yl)oxazolidin-2-one (0.170 g, 48%) was prepared by the procedure described in Example 1, Step 4, substituting 5-methyloxazolidin-2-one (0.494 g, 4.88 mmol) for (S)-4-isopropyloxazolidin-2-one and 5-chloropyrazolo[1,5-a]pyrimidine (0.250 g, 1.63 mmol) for 3-bromo-5-chloropyrazolo[1,5-a]pyrimidine.
