To a solution of (S)-5-(4-cyclohexyl-phenoxymethyl)-4,5-dihydro-oxazol-2-ylamine (0.5 g, 1.82 mmol) in t-butanol (5 mL) was added 4-ethylsulfanyl-but-2-ynoic acid ethyl ester (0.411 g, 2.39 mmol). The reaction mixture was heated in a microwave oven at 170° C. for 20 min. The solvent was removed under vacuum, and the residue purified by flash column chromatography (silica gel, MeOH/CH2Cl2) to afford 0.416 g of the title compound.
