Versuchsvorschrift
A solution of [[5-(N,N-dimethylaminomethyl)2-thienyl]methoxy] acetic acid ethyl ester (4.0 g) in a mixture of 0.88 ammonia solution (75 ml) and ethanol (75 ml) was stirred for 1 hr at room temperature. The solvent was removed and the residue recrystallised from a 1:1 mixture of benzene and petroleum spirit (b.p. 60°-80°) to afford a white crystalline solid (3.2 g) m.p. 86.5°-95°. NMR (CDCl3) 7.71, s, (6H); 6.38, s, (2H); 6.00, s, (2H); 5.30, s, (2H); 3.5, br, (2H); 3.12, q, (2H).
