Reaction Steps

Phenyl{6-[(3,3,7-trimethyl-2,3-dihydro-1-benzofuran-4-yl)oxy]-3-pyridinyl}carbamate (Intermediate 1, 640 mg, 1.64 mmol) was dissolved in dioxane (7 mL) and hydrazine monohydrate (8.2 mmol) was added. The reaction mixture was stirred for 30 minutes at room temperature and then at 70° C. for 1 hour. Water was added and the resulting suspension was stirred for 1 hour and then filtered. The solid was collected, washed with water and dried under vacuum at 25° C. affording the title compound (340 mg) as off-white solid.
