実験手順
To a stirred solution of 6-cyano-6H-dibenzo[b,d]thiopyran (4.5 g; 0.02 mol) and CH3I (28.4 g; 0.2 mol) in 100 ml of dimethylformamide, 50% NaH (1.5 g; 0.03 mol) was added in small portions. After 16 hours at room temperature the mixture was poured into water and extracted with diethyl ether. The organic phase was washed with water and dried over Na2SO4. Evaporation of the solvent gave 6-cyano-6-methyl-6H-dibenzo[b,d]thiopyran (3.58 g; 0.015 mol; yield 75%).
