Reaction Steps

A solution of 3-(3,5-dimethyl-4-oxiranylmethoxy-phenyl)-5-(5,5-dimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-[1,2,4]oxadiazole (500 mg, 1.18 mmol) in 2 N methanolic ammonia (7 mL) is heated in a sealed vial to 100° C. for 5 min in a microwave oven (300 W, active cooling during irradiation). The solvent is evaporated and the residue is purified by prep. HPLC (GROM-SIL ODS-4 HE, 75×30 mm ID, 10 μm, 20-95% acetonitrile in water containing 0.5% formic acid) to afford 1-amino-3-{4-[5-(5,5-dimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-[1,2,4]oxadiazol-3-yl]-2,6-dimethyl-phenoxy}-propan-2-ol (220 mg) as a colourless resin; LC-MS: tR=0.92 min, [M+1]+=428.38.
