Procedure

A solution of tert-butyl 2-(4-chlorophenyl)-2-(6-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)benzo[d]isothiazol-3-yl)ethylcarbamate (41 mg, 0.076 mmol) in DCM was treated with 4N HCl in dioxane (0.5 mL). The reaction was stirred at room temperature overnight. The reaction was concentrated and triturated with ether (twice) to yield (5R,7R)-4-(3-(2-amino-1-(4-chlorophenyl)ethyl)benzo[d]isothiazol-6-yl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol trihydrochloride (32 mg, 77%). LCMS (APCI+) m/z 437, 439 [M+H]+; Rt=2.48 min.
