888952-55-4, To a solution of LDA (lithium diisopropylamide) (prepared by mixing 0.64 mL of i-Pr2NH and 2.7 mL of a 1.6 M solution of n-BuLi in hexanes in 4 mL of anhydrous THF) at -78 C. under N2 was added a solution of 1-(1,1-dimethylethyl) 3-methyl 1,3-piperidinedicarboxylate (prepared as in U.S. Pat. No. 5,190,953, 1.009 g, 4.15 mmol) in 6 mL of anhydrous THF. The reaction mixture was stirred at -78 C. for 30 min. A solution of 2-Chloro-4-phenylquinazoline (1.002 g, 4.16 mmol) in 8 mL of anhydrous THF was then added dropwise into the reaction mixture at -78 C. The reaction mixture was stirred at -78 C. for 20 min. and then slowly warmed to room temperature in 3 hours. The mixture was cooled back to 0 C. Saturated NH4Cl solution was added to quench the reaction. The mixture was extracted with EtOAc (2*50 mL). The combined organic extracts was dried with MgSO4, filtered and concentrated. The residue was chromatographed on silica gel with 10% ethyl acetate in hexanes to remove the unreacted 2-Chloro-4-phenylquinazoline. The column was then eluted with 20% ethyl acetate in hexanes to give 1.803 g of product as a white foam. APCI MS m/z 348, 392, 448 (M++1, 100%).
888952-55-4 Methyl 1-Boc-3-methylpiperidine-3-carboxylate 46911995, apiperidines compound, is more and more widely used in various fields.
