A mixture of 2-methyl-1-(2-morpholinophenyl)-2-thiopseudourea hydroiodide (3.8 g prepared as described in Example 166), 3-methylaminopropylamine (2.6 g) and absolute ethanol (40 ml) was heated under reflux for 6 hours to give a solid which was recrystallised from ether to give 4-[2-(1-methylperhydropyrimidin-2-ylideneamino)phenyl]morpholine (m.p. 138°-139° C.).
