Procedure

(1S,6S)-4,6-Dimethyl-cyclohex-3-ene-carboxylic acid [5-(3,3-dimethyl-but-1-ynyl)-thiophen-3-yl]-(1,4-dioxa-spiro[4.5]dec-8-yl)-amide (5.6 g, 12 mmol) was dissolved in THF (70 mL) and treated with 4M HCl (35 mL). The reaction mixture was heated to 45° C. and stirred for 2.5 h. THF was removed in vacuo, and the aqueous layer was thrice extracted into ethyl acetate. The combined organic layers were washed with saturated NaHCO3(aq), water, and brine, dried over MgSO4, filtered, and concentrated to give (1S,6S)-4,6-dimethyl-cyclohex-3-ene-carboxylic acid [5-(3,3-dimethyl-but-1-ynyl)-thiophen-3-yl]-(4-oxo-cyclohexyl)-amide (5.05 g, 12 mmol).
