Yield:90002-06-5 96%

Reaction Conditions:

in toluene; for 2 h;Reflux;Molecular sieve;

Steps:

239.3

Step-3: The step-2 product (18 g, 85 mmol) was refluxed in toluene (200 ml) along with 4 molecular sieves for 2 hrs. The reaction mixture was concentrated under vacuum to provide a crude residue. The crude residue was triturated with diethyl ether to afford 5-chloromethyl-1,2,4-oxadiazol-3-yl)-pyridine, as step-3 product as a off white solid in 96% (16 g) yield. MS: m/z: 197.6 (M+1).
