Procedure

3,4-Dihydro-2-dimethylaminomethylene-7-methyl-1(2H) naphthalenone was prepared from 7-methyl-1-tetralone (4.8 g, 30 mmol) and N,N-dimethyl-formamide diethyl acetal (15.4 ml, 90 mmol). The crude product was recrystallised from diethyl ether-hexane to give yellow crystals (4.64 g) m.p. 79-82° MS (ES+) 238 (MNa+, 6%), 216 (MH+, 100%).
