HCID 54074535HCID 54074535, compound

Procedure

The 3,4-dihydro-4,4-dimethyl-2-dimethylaminomethylene-7-methoxy-1 (2H) naphthalenone was prepared from 4,4-dimethyl-7-methoxy-1-tetralone [2.3 g; H. Hart et al J. Chem. Soc. 85, 3260, (1963)] and N,N-dimethylformamide diethylacetal (6 ml) in a method analogous to that used in Example 1, to give the desired product as a yellow solid (2.26 g) m.p. 108-110°. MS (ES+) 260 (MH+, 100%).
