Reaction Steps

The 2,5-dimethoxy-tetrahydrofuran (106 g, 80 mmol) was added to the solution of 4-amino-3-methylbenzamide (100 g, 66.7 mmol) in AcOH (300 mL). The mixture was stirred at 80° C. for about 1.5 h and then cooled to room temperature. The solution of Na2CO3 was added dropwise at 0° C. and extracted with ethyl acetate for three times. The combined organic layers were washed with brine, dried over Na2SO4, concentrated and washed with petroleum ether. The resultant solid was filtrated and dried to afford 3-methyl-4-(1H-pyrrol-1-yl)benzamide as a pale solid (89.7 g, yield 67%).
