Reaction Steps

A mixture of 2,4-dichloro-7-methoxy-quinoline (1.34 g, 5.88 mmol) and isopropyl-(1H-pyrazol-3-yl)-amine (1.10 g, 8.80 mmol) was heated at 115° C. for 3 h while stirring in a sealed tube. After ˜20 min. of heating, the pressure built up in the tube was released by using a needle. The mixture was then dissolved in dichloromethane and loaded onto a silica gel column. Elution with dichloromethane and methanol afforded [1-(4-chloro-7-methoxy-quinolin-2-yl)-1H-pyrazol-3-yl]-isopropyl-amine (1.53 g, 82%). LC/MS=317.2 (M++1).
