H2O2 (30% 11.3 mL, 118 mmol) was added over 3 h to a stirred mixture of nitrile 1-2c (13.88 g, ˜58.9 mmol) and K2CO3 (1.62 g, 11.8 mol) in 59 mL of DMSO at 40-87° C., cooling with a water bath. The resulting mixture was cooled to 27° C. and water (100 mL) was added over 30 min. Crystalline product 1-3c formed. More water (100 mL) was added over 1 h. The resulting slurry was aged at RT for 16 h before filtration. The cake was rinsed with 100 mL of water and then with 100 mL of heptane. After drying in a vacuum oven at 50° C., product 1-3c was obtained as a white solid.
