Reaction Steps

N-[2,2-Dimethyl-5-(2-{4-[5-(4-methylbenzoyl)-2-thienyl]phenyl}ethyl)-1,3-dioxan-5-yl]acetamide (0.22 g) was dissolved in ethanol (4 mL), concentrated hydrochloric acid (2 mL) was added, and the mixture was stirred at 80° C. for 4 hr. The reaction mixture was concentrated, aqueous potassium carbonate solution was added to the residue, and the precipitated crystals were collected by filtration to give the title compound (163 mg) as brown crystals.
