反応手順
8-Methyl-1,4-dioxa-spiro[4.5]decane-8-carboxylic acid ethyl ester (Compound 282G) was dissolved in THF (20 mL) and 3N aq. HCl (30 mL). The resulting mixture was stirred at rt overnight. The mixture was diluted with EtOAc (50 mL), washed with brine (20 mL), and dried over anhydrous sodium sulfate. 1H NMR (CDCl3): 1.28 (t, J=7.1 Hz, 3H), 1.29 (s, 3H), 1.63-1.70 (m, 2H), 2.30-2.74 (m, 6H), 3.94 (s, 4H), 4.19 (q, J=7.1 Hz, 2H).
