develop a separation protocol. Upon extraction of the acylated products, the 3′-O-methyladenosine was isolated in 81 % yield and 97 % purity from the aqueous layer. Hydrolysis of acylated products in organic layer furnished 2′-O-methyladenosine in 67 % yield and 99 % purity. The separation process was successfully applied to the crude reaction mixture of methylated products (ca. 3:1 of 1/2) on 5-g scale
