Steps:
14 Synthesis of 4-methoxypyridine 1-oxide
Synthesis of 4-methoxypyridine 1-oxide [0320] To a stirred solution of 4-methoxypyridine (5 g, 45.87 mmol) in acetic acid (25 mL) under argon atmosphere was added a 30%> hydrogen peroxide solution (4.2 mL) at RT. The reaction mixture was stirred at reflux for 24 h. After the consumption of the starting materials (monitored by TLC), the volatile components were removed in vacuo to afford 4- methoxypyridine 1-oxide (5 g, 88%>) as a yellow liquid. LC-MS: 125.9 (M+l); (column; Eclipse XDB C-18 (150 4.6 mm, 5.0 μιη); RT 5.02 min. 0.05% Aq TFA: ACN; 1.0 mL/min); TLC: 5% MeOH:CH2Cl2 (R 0.1).
