Reaction Steps

DEAD (0.24 ml, 1.51 mmol) was slowly added to a mixture of methyl 2-hydroxy-5-[(4-methyl-1-piperazinyl)sulfonyl]benzoate (may be prepared as described in Description 70; 430 mg, 1.37 mmol), Ph3P (395 mg, 1.51 mmol) and phenylmethanol (163 mg, 1.505 mmol) in toluene (15 ml) cooled in an ice bath at 0° C. The mixture was stirred for 2 h at room temperature. Ether was added to the mixture and the mixture was filtered. The filtrate was evaporated to yield the title compound. 260 mg.
