Reaction Steps

4-Isoxazol-3-ylphenylamine (Intermediate 5, 4 g, 24.69 mmol) was added to dichloromethane (20 ml) followed by pyridine (4.6 ml). The solution was cooled to 0° C. and benzyl chloroformate (5.27 ml, 37.02 mmol) was added drop wise. The solution was allowed to stir for 2 hours at room temperature and then concentrated under vacuum. The residue was added to 30 ml of 1:1 hexane:EtOAc mixture. The crystals were collected by filtration to yield the product (2.26 g).
