Reaction Steps

A mixture of 6-bromo-2-phenyl-2′-thioxospiro[chroman-4,4′-imidazolidin]-5′-one (250 mg, 0.644 mmol), excess (2-bromoethyl)cyclopropane (381 mg, 2.58 mmol), and solid K2CO3 (356 mg, 2.58 mmol) in CH3CN (10 mL) was stirred for 4 hours at 60° C. The mixture was filtered and the filtrate was concentrated. The crude product was purified by preparative TLC to give 6-bromo-1′-(2-cyclopropylethyl)-2′-(2-cyclopropylethylthio)-2-phenylspiro[chroman-4,4′-imidazol]-5′(1′H)-one (40 mg, 11%).
