Reaction Conditions

Reaction Steps

A mixture of 2-iodo-4-(tetrahydro-2H-pyran-4-ylmethyl)aniline (1.0 g) and diethyl ethoxymethylenemalonate (0.70 mL) is heated at 130° C. for 1 h. The mixture is cooled to room temperature. Diphenyl ether (20 mL) is added and the reaction is heated to 250° C. for 1 h. The mixture is cooled and the resulting solid is collected and washed with hexanes. The crude product is chromatographed (Biotage flash 40M, eluent 2% MeOH/CH2Cl2) to yield 0.80 g (58%) of the desired product as an off-white solid.
