The procedure described in Example 15-1 was followed except that 4-methyl-2-nitro-thiobenzamide (56) was used instead of 4-trifluoromethyl-2-nitro-thiobenzamide, bromoacetaldehyde-dimethylacetal was used instead of 1-bromo-3-methyl-butan-2-one, and the reaction was acid catalyst with 5% acetic acid. This gave the title compound (66 mg, 75%). LC/MS: (Method I): tR=0.98 min, >90%, m/z (ESI+)=221 (MH+).
