Reaction Steps

A solution of 3-nitrophenylcarboxamide (2 g) in 25 ml of dry tetrahydrofuran was cooled to 0° C. and treated with 648 mg of sodium hydride (60% oil dispersion). The reaction mixture was stirred for 15 minutes and then 2-propylisocyanate (1.48 ml) was introduced dropwise via syringe. The reaction mixture was then stirred at 0° C. overnight. The reaction mixture was diluted with 300 ml of ethyl acetate. The reaction mixture was washed with 10% citric acid solution and brine. The organic extracts were dried and then concentrated in vacuo to yield 3.9 g of the title compound in sufficient purity to be used in the next step.
