反応手順
2.2 G. of 2-hydroxymethyl-3,4,5-trimethyl-thiophene were dissolved in 25 ml. of acetonitrile and 4.6 g. of triphenylphosphonium bromide were added. The resulting reaction mixture was heated to 50° C. for 3 hours. After evaporation of the solvent, the residue which formed was diluted with ethyl acetate, heated briefly and filtered. The crystalline (3,4,5-trimethyl-2-thenyl)-triphenyl phosphonium bromide obtained was dried at 50° C. under high vacuum and had m.p. 208°-215° C.
