After cooling the mixture in an ice bath the precipitate formed was filtered off and washed with ice cold ethanol. The filtrate was evaporated to dryness to yield N1-(7-methoxy-3-(2-(methylamino)pyrimidin-4-yl)naphthalen-1-yl) propane-1,3-diamine 182 as a yellow solid which was used in the next step without further purification.
