Reaction Steps

15 g of 2-methoxy-5-methoxycarbonylaniline are dissolved in 500 ml of propionic acid under argon and at room temperature and 15.7 g of sodium borohydride are added in small portions. The reaction mixture is stirred for 2 hours and then hydrolyzed and alkalinized with 10 N sodium hydroxide while the temperature is maintained below 20° C. It is extracted with dichloromethane, the organic phase is washed with a saturated NaCl solution, dried and then evaporated under vacuum. The expected product is obtained in the form of an oil with a quantitative yield.
