Reaction Steps

A solution of (6,7,8,9-tetrahydro-pyrido[1,2-a]indol-8-yl)-carbamic acid tert-butyl ester (400 mg, 1.40 mmol) in dry THF (5 mL) was cooled to 0° C. Triphosgene (208 mg, 0.7 mmol) dissolved in dry THF (3 mL) and triethylamine (194 μL, 1.40 mmole) were added. A precipitation was formed. The reaction was allowed to reach room temperature and after 2 h the mixture was evaporated and the crude product was used in the next step. APCI-MS m/z: 345 [MH+] (analysis performed on a sample quenched with methanol, thus the mass corresponds to the methylester).
