실험 절차

2-Methoxy-4-methylnicotinaldehyde (1.8 g, 12 mmol), tert-butylamine (15 mL), 3 Å molecular sieves (8 g) and dry DCM (10 mL) were mixed and allowed to stand at RT under protection from moisture (calcium chloride tube). After two days the mixture was filtered and the molecular sieves were washed several times with dry DCM. The combined washings were concentrated to give 2.2 g (89%) of the title compound as a crude oil that was used immediately in the next step.
