Recommanded Product: tert-Butyl sulfamoylcarbamate

(S)-(6-chloro-2,3-dihydrobenzo[b][1 ,4]dioxin-2-yl)methanol (20.0 g, 100.0 mmol, 1 .0 eq.), tert-butoxycarbonyl sulfamide (27.4 g, 140.0 mmol, 1 .4 eq) and triphenylphosphine (3.9 g, 1 18.0 mmol, 1 .2 eq,) were dissolved in MTBE (140 g) and the resulting mixture was warmed under stirring to a temperature in the range of 27-32C. Diisopropyl-azodicarboxylate (22.6 g, 1 1 1 .0 mmol, 1 .1 1 eq) in MTBE (18 g) was added dropwise over about 60-120 min, while maintaining the temperature of the reaction mixture in the range of about 27-32C. The resulting mixture was then stirred for 2-6 hours, cooled to a temperature in the range of about 15-20C. The resulting mixture was then seeded with triphenylphosphinoxide and bis-1,2-(isopropoxycarbonyl)-hydrazine (which were taken from previously prepared batches) and stirred for an additional hour. After the onset of crystallization was confirmed, n-hexane (80 g) was added over about 45-60 min, after which time, the resulting suspension was stirred for an additional 120 min at a temperature of about 15-20C. The resulting mixture was then cooled to a temperature in the range of -15 to -10C and stirred for about 4-6 hours. The resulting off-white solid was filtered off and washed with a cold mixture of MTBE (20 g) and n-hexane (10 g). At 50C and a pressure of about 450-400 mbar a total of 240 g of solvent was distilled off from the resulting filtrate. To the resulting concentrated residue were added toluene (100 g) and n-hexane (15 g). The resulting solution, at a temperature of about 22-27C, was washed with a mixture of methanol (40 g) and water (60 g). This step was then repeated twice (2X). At a temperature of about 45C and at about 250-100 mbar pressure, about 90 g of solvent were distilled off to yield a concentrated residue containing the desired product.

The synthetic route of 148017-28-1 has been constantly updated, and we look forward to future research findings.
