Versuchsvorschrift

Following the basic procedure of Example 11(d), by reacting 2.9 g (12 mmol) of α-ethynyl-5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenemethanol with 3.2 g (12.1 mmol) of methyl N-methyl-4-iodo-2-pyrrolecarboxylate, 2.8 g (61%) of the expected ester, with a melting point of 150°-152° C., were recovered by trituration in isopropyl ether.
