実験手順
Compound 21 was synthesized similar to the procedure described in Example 1 for the preparation of compound 2 using compound 20 rather than compound 1. After isolation, 3.76 g of compound 21 (82.5%) was obtained with a purity of 92.7% as an off-white solid A sample was further purified by column chromatography to afford compound 21 in >99% purity as a white solid.
