To a degassed solution of 174.7 mg (0.424 mmol) of (3S,4R,6R)-4-(3-chlorophenyl)-3-(4-chlorophenyl)-6-methyl-2-(2-propanyl)-1,2-thiazinan (Example 120, Step A) in THF (1.5 mL) was added allyl iodide (0.55 mL, 6.02 mmol). The resulting solution was heated to 60° C. for 10 minutes, then a 1 M solution of lithium bis(trimethylsilyl)-amide in THF (2.0 mL, 2.00 mmol) was added dropwise, over one minute. After heating at 60° C. for 17 hours, the reaction was cooled to room temperature, quenched with water (2 mL), and then concentrated under reduced pressure. Purification by reverse-phase preparative HPLC using an Agilent Eclipse Plus C18 column (Agilent Technologies, Santa, Clara, Calif.), 0.1% TFA in MeCN/H2O, gradient 40% to 95% over 25 minutes, provided the title compound as a white solid.
