Participants

Reaction Steps

According to a similar procedure to that described in Example 1-(12), 4-[(1E,3E)-4-[trans-5-[[(1R,2R)-2-(2,4-difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl]thio]-1,3-dioxan-2-yl]-1,3-butadienyl]-3-fluorobenzonitrile (1.09 g, 2.0 mmol) described in Reference example 1, sodium hydride (55% dispersion in mineral oil; 104.7 mg, 2.4 mmol), and 4-[[bis(allyloxy)phosphoryl]oxy]-2,2-dimethylbutyl chloride were reacted in tetrahydrofuran (10 ml) and the reaction mixture was worked up to afford, after extraction, the title compound as a crude oil. The crude oily product was subjected to chromatography on a silica gel (75 g) column (eluent; ethyl acetate:hexane=2:1˜3:1) to afford the title compound (238.8 mg, 15% yield) as a pale yellow amorphous solid.
