実験手順

1-Chloroethyl chloroformate (543 mg, 3.8 mmol) was added dropwise to a mixture of 7-benzyl-N-(4-(trifluoromethyl)phenyl)-5,6,7,8-tetrahydro-2-(methoxymethyl)pyrido[3,4-d]pyrimidin-4-amine from Example 31 (820 mg, 1.9 mmol) and diisopropylethyl amine (490 mg, 3.8 mmol) in 1,2-dichloroethane (5 mL, anhydrous) at room temperature. After addition, the reaction mixture was stirred at 60° C. for 2 h under nitrogen. Solvent was removed in vacuo, residue was dissolved in methanol (10 mL) and was stirred at 60° C. for 1 hr. Solvent was removed in vacuo, residue was dissolved in ethyl acetate and was washed with saturated aqueous sodium bicarbonate, brine and dried over sodium sulfate. Solvent was removed in vacuo and light orange oily residue which was usd directly in the next step.
