Versuchsvorschrift

Sodium ethoxide (0.18 g) was added to a stirred solution of N′-acetyl-N-(2-methylpropyl)-N-[3-ethoxycarbonyl-5-(1-naphthalenylmethyl)-2-thienyl]urea (Example 3, step c), 0.30 g) in ethanol (6 ml). After 6 hours, iodomethane (0.165 ml) was added. After a further 16 hours iodomethane (0.165 ml) was added, After a further 24 hours, the reaction mixture was poured onto hydrochloric acid (2M, 30 ml) and extracted with ethyl acetate (2×30 ml). The organic extracts were dried over anhydrous magnesium sulfate, filtered and evaporated under reduced pressure. The residue was purified by column chromatography over silica, eluting with ether:hexane (1:1) and then triturated with ether to give the title compound (0.24 g).
