Reaction Steps
1-{3-[(1-Isopropylpiperidin-4-yl)oxy]phenyl}methanamine (188 mg, 0.757 mmol) and methyl 5-(4-chlorophenyl)-3-{[(1E)-(dimethylamino)methylene]amino}thiophene-2-carboxylate (244 mg, 0.757 mmol) were dissolved in MeOH (2 ml). The reaction was heated in a microwave at 120° C. for 15 minutes, during which time a precipitate had been formed in the microwave vial. The precipitate was filtered off and washed with MeOH. The filtrate was purified by reversed phase HPLC yielding the title compound as a white solid.
