Procedure

To a solution of ethyl 2-((R)-1-((S)-4-(4-chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-ylamino)thiazole-4-carboxylate (69 mg, 0.140 mmol) in MeOH (0.28 ml)/THF (0.280 ml) was added NaOH, 1N (0.140 ml, 0.140 mmol) and the reaction stirred at room temperature. The reaction was stirred for 8 h and then neutralized with 1 N HCL. The solvents were removed and water (˜1 mL) was added. The resulting solids were stirred and sonicated briefly, filtered and rinsed with water. HPLC purity of crude solids, ˜90%; MS found: 466.26 (M+)+.
