Procedure
To a suspension of a HBr salt of 2-[2-(2-amino-thiazol-5-yl)-ethyl]-isoindole-1,3-dione (compound 58.1; 1.42 mmol) in dichloromethane was added TEA (4.30 mmol) followed by the addition of phenyl chloroformate (1.43 mmol) at room temperature. After 2 hours, the reaction was concentrated to dryness to give a solid that was suspended in EtOAc, filtered, washed with additional EtOAc and dried under vacuum to provide {5-[2-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-ethyl]-thiazol-2-yl}-carbamic acid phenyl ester (compound 58.2, which is contaminated with triethyl amine salts) which was used in the next reaction without further purification.
