Reaction Steps
Following the procedure as described in step A of Preparation 14, making variations as required to replace 4-(chloromethyl)pyrimidine with 2-(chloromethyl)pyrazine (prepared according to R. W. Carling, et al., J. Med. Chem., (2004), Vol. 47, pp. 1807-1822) to react with potassium phthalimide, 2-(pyrazin-2-ylmethyl)isoindoline-1,3-dione was obtained as a colorless solid in 46% yield: mp 141-143° C.; 1H NMR (300 MHz, CDCl3) δ 8.65 (s, 1H), 8.47 (s, 2H), 7.90-7.87 (m, 2H), 7.76-7.73 (m, 2H), 5.05 (s, 2H); MS (ES+) m/z 240.1 (M+1).
