実験手順

Prepared using General Procedure 8. To a stirred solution of (S)-5-(5-(1-amino-2,3-dihydro-1H-inden-4-yl)-1,3,4-thiadiazol-2-yl)-2-isopropoxybenzonitrile hydrochloride 4 (15 mg, 0.03 mmol) and TEA (11 mg, 0.1 mmol) in DCM (1 mL) was added methyl chloroformate (10 mg, 0.1). The reaction mixture was stirred at room temperature for 16 h. The solvent was evaporated and water (2 mL) was added. The resulting solid was filtered, washed with water, and dried under high vacuum to afford 12 mg (92%) of (S)-methyl(4-(5-(3-cyano-4-isopropoxyphenyl)-1,3,4-thiadiazol-2-yl)-2,3-dihydro-1H-inden-1-yl)carbamate 16 as white solid. LCMS-ESI (m/z) calculated for C23H22N4O3S: 434.1; found 435.3 [M+H]+, tR=3.69 min.
