Reaction Steps

N-[(1R,2R)-3-{[tert-butyl(diphenyl)silyl]oxy}-2-methyl-1-phenylpropyl]-2-methylpropane-2-sulfinamide (Example 136b, 1.46 g) was stirred in methanol (10 mL) and then Hydrogen chloride (4M in dioxane) (10 mL) added. The reaction was stirred at 70° C. for 7 h and then concentrated in vacuo. The crude product was azeotroped with toluene then triturated in ether for 2 days after which the solvent was concentrated in vacuo to give the subtitle compound (0.47 g).
