Procedure

To a stirred mixture of 1.0 g (3.5 mmol) of 2-amino-6-(3-(3-pyridyl)allyl)-4,5,7,8-tetrahydro-6H- thiazolo[5,4-d]azepine and 0.53 ml (3.8 mmol) of triethylamine in 40 ml of anhydrous chloroform, there is added dropwise at ambient temperature a solution of 3- (4-methoxy-phenyl)-propionyl chloride (bp: 150° C./15 torr) in 7 ml of chloroform. The mixture is stirred for 3 hours at 60°-70° C., cooled and extracted with water. The dried and filtered chloroform solution is evaporated down in vacuo and the evaporation residue is purified by column chromatography on silica gel (chloroform/methanol=5:1). Yield: 0.74 g (47% of theory), Melting point: 168°-170° C. (ether).
