    • 2 as an eluent to provide pure product 7 as a white solid (1.8 g, 79%). The NMR spectrum of 7 was identical with the data reported in Refs: (a) Liu, Y.; Zou, L.; Ma, L.; Chen, W.-H.; Wang, B.; Xu, Z.-L. Bioorg. Med. Chem. 2006, 14, 5683-5690; (b) Fatel, G. F.; Trivedi, K. N. Synth. Commun. 1989, 19, 1641-1647. This reaction appears to be an improved method to synthesis xanthone derivatives such as 7, since the current literature examples typically give low yield and by-products.
