Reaction Conditions

Reaction Steps

A 0.25 L flask fitted with a thermometer, condenser, magnetic stirring, and nitrogen inlet was charged with 4.92 g 5-Fluorooxindole, 7.0 g Imidazole amide, 15.5 g (R)-1-Amino-3-(4-morpholinyl)-2-propanol, 9.78 g Triethylamine and 88 ml Tetrahydrofuran. The mixture was heated to 60° C. for 16.5 hours. The reaction is cooled to ambient temperature and filtered. The solids obtained are slurried (3) three successive times in acetonitrile at 11 ml/g, dried in vacuo for 3.6 g (25.25%).
