Diethylamine → HCID 68427031, compound

Participants

Reaction Steps

3.62 g of the entitled compound was obtained as a pale orange solid from the latter fraction (retention time: 14.8 min) in the same method as in Production Example 25-3, for which, however, tert-butyl 4-(2-chloro-4-fluorophenyl)-3,6-dihydro-2H-pyridine-1-carboxylate was used in place of tert-butyl 4-(2-chlorophenyl)-3,6-dihydro-2H-pyridine-1-carboxylate used in Production Example 25-3, and an optically-active column (Daicel's CHRALPAK AD column, 2 cm×25 cm; 0.1% diethylamine, hexane/ethanol=9/1; flow rate, 20 mL/min) was sued for the optical resolution.
