Procedure

By reacting 1.2 g. (2 mmole) p-nitrophenyl 8-benzyloxy-3,3-dimethyl-6-(5-phenyl-2-pentyloxy)tetralin-1-carboxylate, 0.3 g. (5 mmole) urea and 0.248 g. (10 mmole) sodium hydride in 12 ml. dimethylsulfoxide at room temperature for one hour and isolation of product by the method of Example 89, Part B and removal of benzyl group by hydrogenolysis by the procedure of Example 89, Part C affords the pure title compound in 36% overall yield. 1H-NMR (CDCl3) ppm (delta): 0.77 (s, 3H), 1.1 (m, 8H), 1.7 (m, 4H), 2.5 (m, 4H), 3.6 (m, 1H), 4.16 (m, 1H), 5.7 (s, 1H), 6.1 (s, 2H), 7.1 (s, 5H), 8.2 (s, 2H).

Workup
