Reaction Steps
Following the procedure of Example 2, 6-chloro-4-cyano-4-trimethylsilyloxy-3,4-dihydro-2H-1-benzothiopyran (5.8 g.) was reacted with stannous chloride dihydrate in glacial acetic acid (25 ml.) and concentrated hydrochloric acid (25 ml.). Recrystallization from benzene:cyclohexane gave 6-chloro-3,4-dihydro-2H-1-benzothiopyran-4-carboxylic acid (2.59 g.), m.p. 153°-154° C.
