Ammonia → 1-Amino-3-{4-[5-(5-ethyl-thiophen-2-yl)-[1,2,4]oxadiazol-3-yl]-2,6-dimethyl-phenoxy}-propan-2-ol

Participants

Reaction Steps

A solution of 3-(3,5-dimethyl-4-oxiranylmethoxy-phenyl)-5-(5-ethyl-thiophen-2-yl)-[1,2,4]oxadiazole (123 mg, 0.345 mmol) in 7 N NH3 in methanol (10 mL) is stirred at 45° C. for 16 h. The solvent is evaporated and the residue is separated by chromatography on prep. TLC plates with DCM containing 6% of 7 N NH3 in methanol to give 1-amino-3-{4-[5-(5-ethyl-thiophen-2-yl)-[1,2,4]oxadiazol-3-yl]-2,6-dimethyl-phenoxy}-propan-2-ol (35 mg) as a white solid; LC-MS: tR=0.84 min, [M+1]+=374.14.
