Participants

Reaction Steps

2.17 Parts of 1,4-dihydro-4-methylthieno-[3,4-b]-quinolin-9(3H)-one are reacted with 0.88 part by volume of sulfuryl chloride in 25 parts by volume of methylene chloride at 0° C. for 0.5 hour. The end product is isolated from the reaction mixture by the method described in Example 5c. 1.50 parts (70% of theory) of 4-methyl-thieno-[3,4-b]-quinolin-9(4H)-one of the melting point 188°-190° C. are obtained.
