Procedure
A solution of 4-[4-[3-(1-imidazolyl)propyl]phenoxymethyl]-2-[(E)-2-(2-thienyl)ethenyl]oxazole (200 mg) in methanol (10 ml)-tetrahydrofuran (4 ml) was hydrogenated on palladium carbon (10%, wet, 70 mg) at 4 atm. After removal of the catalyst by filtration, the filtrate was concentrated. The hydrogenation was repeated three times to obtain 4-[4-[3-(1-imidazolyl)propyl]phenoxymethyl]-2-[2-(2-thienyl)ethyl]oxazole. Recrystallization from ethyl acetate-methanol gave colorless prisms (155 mg, 79%), mp 68-70° C.
