実験手順

N-Thionylaniline (2.6 mL, 23.2 mmol) is added to amino(1-triphenylmethyl-1,4,5,6-tetrahydropyrimidin-5-yl)acetamide (1.64 g, 4.1 mmol) suspended in pyridine (25 ml). After heating at 90° C. for 48 hours the pyridine is evaporated, and the black residue partitioned between chloroform and water. The aqueous layer is lowered to pH 5 (HCl) and chromatographed (Dowex-50 W, 0.5 N ammonium hydroxide) to yield the product as a brown solid 1.05 g (61%) that can be further purified by chromatography (silica, methanol) and converted to a white crystalline hydrochloride salt, ms m/z=426.
