Reaction Steps

A mixture of 2-nitro-5-propoxy-benzoic acid (1.97 g, 8.75 mmol) and DMF (0.1 mL) in SOCl2 (20 mL) was stirred at 65° C. for 2 h. After the reaction was completed, the mixture was cooled to room temperature. SOCl2 was removed in vacuo and the residue was dissolved in anhydrous CH2Cl2 (10 mL), which was added to NH3—H2O (28%) dropwise. After 1 h, the precipitate was collected and dried in vacuo to give 1.68 g of i-a as a yellow solid (85.2%). LCMS m/z=208.1 (M−16), 225.1 (M+1) (Method B) (retention time=1.88 min).
