Reaction Steps

The product from Step (c) (0.25 g, 1.0 mmol), urea (90 mg, 1.5 mmol) and Ytterbium trifluoromethanesulfonate (62 mg, 0.1 mmol) were combined in acetonitrile (5 ml) and 4-Fluorobenzaldehyde (0.11 ml, 1.0 mmol) was added to the mixture. The reaction mixture was sealed and heated to 100° C. for 3 hours. The reaction was diluted with water (1 ml) and the solid product was collected by filtration. The solid was washed three times with 1:1 Et2O/CH3CN to afford the title compound, (0.34 g, 85%); MS (ES+) m/e 401 [M+H]+.
