실험 절차

A 1 M solution of tin chloride in CH2Cl2 (1.3 mL, 1.3 mmol) was added dropwise to an ice water cooled solution of p-toluoyl chloride (10.00 g, 65 mmol) and TMSCN (9.00 mL, 68 mmol). The reaction was monitored to completion over 4 hours by disappearance of the IR acid chloride carbonyl stretch, then quenched by addition of ice water (20 mL) and extracted with CH2Cl2. The organic solution was dried (MgSO4) and concentrated to afford 8.80 g of p-toluoyl cyanide as an orange solid.
