실험 절차
The intermediate methyl 5-methylamino-nicotinate has been obtained as follows: reaction of methylamine (40% in water) with 5-bromo-nicotinic acid in autoclave at 140° C. for seven hours gives 5-methylamino-nicotinic acid, m.p. 239°-242° C. from ethanol/water; this acid reacts with SOCl in methanol under reflux for seven hours to afford the ester (methyl 5-methylaminonicotinate; m.p. 113°-115° C., from petroleum ether.
