반응 단계
Methyl 2-(2-chlorobenzyliden)acetoacetate (40.6 g; 169.9 mmol) was condensed with ethyl 3-amino-4-[2-(phthalimido)ethoxy]crotonate (51.5 g; 161.8 mmol) in 2-propanol (160 ml) under reflux for 11 hours. Methanol (103 ml) was added and mixture was cooled to 5/0° C. The solid was filtered off and dried at 40° C. Phthaloyl Amlodipine (60.7 g, purity: 98.6%; 0.86% of impurity HA) was obtained.
