Step c) Preparation of isopropyl pinacol borate: triisopropyl borate (261.0 g, 1.388 mol) and pinacol (142.5 g, 1.207 mol) were added to a 20 L four-necked flask, and the mixture was heated to about 90 °C and maintained for 12 to 16 hours. The progress of the reaction was monitored by gas chromatography (GC), and the completion of the reaction was measured by a pinacol content of less than 4.0%. Upon completion of the reaction, a distillation operation was performed to collect fractions with boiling points between 174 and 178 °C to obtain the target product isopropanol pinacol borate as a colorless oil. Yields ranged from 80-90% in six 20 L batches of the operation.GC analysis showed a product purity of 87-96%, while 1H NMR analysis indicated an extremely high product purity. [The difference between GC purity and 1H NMR purity is attributed to the instability of the product under GC conditions].
