実験手順

2-Methylsulfanyl-7-(3-trifluoromethyl-pyridin-2-yl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepin-4-ol. To solution of 5-oxo-1-(3-trifluoromethyl-pyridin-2-yl)-azepane-4-carboxylic acid ethyl ester (3.0 g, 9.09 mmol) in EtOH (40 mL) was added NaOEt (1.97 g, 29.1 mmol) and thiourea (1.1 g, 13.6 mmol). The mixture was heated at reflux for 12 h. The mixture was cooled, treated with Mel (0.74 mL, 11.8 mmol) drop-wise, and stirred at rt for 1 h. Thee mixture was concentrated and the residue was dissolved in water and acidified to pH=7 with HOAc (a precipitate formed). The solid was filtered to give the title compound (3.3 g, >99%), which was used in the next step without further purification.
