A solution of phenol (13.16 g) in DMF (10 ml) was added in portions over 10 minutes to a stirred suspension of sodium hydride (3.12 g) in DMF (100 ml). After 2 hours, a solution of 3-(chloromethyl)thiophene (14.50 g) in DMF (30 ml) was added in one portion and the resulting mixture was stirred at room temperature for 3 hours then poured into water and extracted with ether. The extracts were washed successively with water, dilute aqueous sodium hydroxide, and aqueous sodium chloride, then dried and concentrated to give 3-(phenoxymethyl)thiophene (18.86 g, 91% yield) as a white solid. An analytical sample, recrystallised from methanol, had mp 49°-50° C.
