Versuchsvorschrift

To crude (S)-tert-butyl 4-(4-(6-((S)-1-tert-butoxy-2-methoxy-2-oxoethyl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-2-yl)pyrimidin-2-yl)-2-methylpiperazine-1-carboxylate in 1,4-dioxane (1.25 mL) was added HCl (0.78 mL of a 4M solution in 1,4-dioxane). The reaction mixture was stirred at room temperature for 2.5 h then concentrated. The resulting solid was suspended in diethyl ether, concentrated and dried under high vacuum overnight. The resulting solid was taken up in water, basified with 2N NaOH, and extracted three times with DCM. The combined organic layers were dried over sodium sulfate, filtered, concentrated, and used without further purification. LCMS-ESI+ calc'd for C30H35ClN5O3S (M+H+): 580.2; Found: 580.2 (M+H+).
