Procedure
Step I (2): Methanolic ammonia (3.33 mL, 23.3 mmol) was added to a flask charged with 5-(4-isothiocyanato-2-methoxyphenyl)-3-methyl-1,2,4-oxadiazole (1.28 g, 5.18 mmol) in MeOH (12 mL). After stirring at rt for 24 h, the reaction mixture was concentrated to dryness in vacuo to afford 1-(3-methoxy-4-(3-methyl-1,2,4-oxadiazol-5-yl)phenyl)thiourea (1.368 g, 5.18 mmol, 100% yield). LC-MS (M+H)+ 265.2. 1H NMR (400 MHz, methanol-d4) δ ppm 7.94 (d, J=8.56 Hz, 1 H) 7.77 (d, J=2.01 Hz, 1 H) 7.06 (dd, J=8.31, 2.01 Hz, 1 H) 3.95 (s, 3 H) 2.40 (s, 3 H).
